When operating a vehicle, it is important to follow all manufacturer's recommendations. One of these recommendations is changing the oil in the axles. The oil in Patriot axles is changed every 50-70 thousand mileage. But it must be remembered that after overcoming a deep ford, an oil change is also necessary. The fact is that when passing a ford, the axle gearboxes are immersed in water and water enters the gearbox through the breather (hole for ventilation of the gearbox). On prepared vehicles, the breather is extended (usually to the highest point) and fords can be stormed with less danger.
To replace it yourself you will need:
- transmission oil;
- special syringe for filling;
- tank or canister for old oil;
- clean rags;
- metal brush.

Experienced owners try to fill 75W140
Share in the comments what kind of oil you use.The front axle will be required 1.5 liters
The rear axle will need 1.33 liters
Before changing the oil, you need to drive the car about 10 kilometers to reach operating temperature. Within 15 minutes after this, change the oil; only at this temperature will you be able to drain the maximum amount of used oil. After carrying out the replacement work, record the mileage readings. Carry out the next replacement after 30 thousand km. mileage
Changing the oil in the front axle of the UAZ Patriot
Replacement procedure:
- Drive your own car onto a lift or repair pit.
- Find the oil filler cap on the front axle housing and remove a layer of dirt from it using a wire brush.
- Remove this cover.
- Place the cork in its place.
- Using a syringe, pour new oil through the filler hole on the crankcase body. According to technical data, the volume of oil in the crankcase should be 1 liter 300 grams. It is necessary to fill the oil until it begins to flow from the oil filler hole.
- Reinstall the oil filler cap in its place.
This completes the oil change in the front axle.
Changing the oil in the rear axle of the UAZ Patriot
Replacement procedure:
- Find the oil filler cap on the crankcase housing in the rear axle and remove a layer of dirt from it using a wire brush.
- Remove the cap from the oil filler hole.
- Unscrew the drain plug, first placing a tank or canister for old oil.
- Drain the old oil.
- Use a wire brush to thoroughly clean the drain plug from metal shavings and dirt.
- Install the plug back.
- Using a syringe, pour new oil into the crankcase filler hole. According to technical data, the volume of oil in the rear axle should be 1 liter 300 grams. It is necessary to fill the oil until it begins to flow from the oil filler hole.
- Reinstall the oil filler cap in its place.
This completes the oil change in the rear axle.
They create a strong lubricating film at the contact points of the parts of these units, which can withstand heavy loads.
Gear oils are defined and differentiated by classifications that are widely accepted today: SAE J306 for viscosity, such as 80W, 90, 75W-85 or 80W-90, and API, which contains a comprehensive rating of gear oils for performance properties, such as GL-4 or GL-5 . In addition, along with the API specification, indicators according to the American military specification, denoted by the MIL index, may sometimes be used. For example MIL-L-2105A or MIL-L-2105B.
Features of the classification of transmission oils according to SAE and API.
SAE viscosity grades with the letter W refer to seasonal oils for the cold season, for example 75W or 80W. Accordingly, without W - to oils for warm summer time, for example 90 or 140. However, since the resource of transmission oils is quite long, using seasonal oils in everyday use, changing them in units every six months, is very inconvenient and not economically profitable.
For these reasons, so-called thickened or all-season transmission oils have become more widespread. They combine the properties of two types of oil at once - summer and winter, which is reflected in their marking, which already consists of two numbers separated by the letter W, for example 75W-90 or 85W-140.
The API classification currently contains five categories - GL-1, GL-2, GL-3, GL-4 and GL-5, which show the applicability and quality level of gear oils. For example, in the GL-5 category - the oil contains extreme pressure, anti-wear and other additives, used for hypoid and other types of gears in gearboxes and cars.
Several types of synchronized gearboxes can be installed on UAZ Hunter cars and all models based on it: a four-speed Russian-made, a five-speed ADS made in China or a five-speed DYMOS made. On the UAZ Patriot and all models based on it, only a Korean-made five-speed DYMOS gearbox is installed.
The UAZ Patriot SUV needs periodic oil changes not only for the engine, gearbox and transfer case, but also for such important units as axles. UAZ Patriot is an all-wheel drive vehicle, but the rear axle is the permanently functioning axle. The front one comes into play if it is necessary to overcome dangerous off-road areas. We will not pay attention to the question of what the structure of SUV axles is, but will consider the following questions: what kind of oil is best to choose for pouring into axles, when such a replacement needs to be carried out and how this process is carried out.
UAZ Patriot is not just a car, but an SUV, in which each mechanism consists of many parts. Axles or a gearbox on an SUV are some kind of containers with oil in which the working elements, that is, gears, operate. Often these devices have two gears, which, due to friction with each other, transmit torque from the transfer case to the wheels.
During the operation of the gears, they are worn out, resulting in the formation of chips or small particles of metal in the containers, that is, inside the bridge. These particles must be removed from these devices so that they do not cause jamming of rotating parts, which will entail not the most pleasant consequences.
Thus, we found out that the lubricating fluid inside the bridge also performs a cleaning function. But this is not the only function of the lubricating fluid in this device. Considerable importance is also given to the process of removing heat from parts that heat up as a result of friction. If during friction the metal reaches a critical temperature value, then it can either lose its original properties or crumble. Therefore, removing heat from heating parts in axles is an important function of the lubricating fluid on the UAZ Patriot SUV.
But even this does not end the functions of the lubricating fluid. Equally important is the direct lubrication of rubbing parts - bearings, gears, shafts that make up the gearbox. Thus, the oil smoothes out the friction process of steel parts, as a result of which the service life of such elements increases tens of times. If there were no oil in the design of the axles of the UAZ Patriot SUV, then every creak of a part would be heard while this steel horse was moving. At the same time, a car without lubricants in the main units would not be able to cover even a few kilometers. Therefore, in this article we will look at what kind of oil needs to be poured into the gearboxes of a UAZ Patriot SUV and how to do it correctly.
Lubricant selection
The designers of the Ulyanovsk Automobile Plant recommend pouring an all-season type of oil with a viscosity grade of SAE 75W/90 according to API GL-5 into the axles of the UAZ Patriot SUV. But what the manufacturer recommends does not mean that you need to use only these types. You need to take this into account, and you can fill in anything, the main thing is that the car drives after that. This is all, of course, a lyrical digression, but it is necessary to find out which oil is best to pour into the Patriot gearbox, and which will be the best and optimal for any buyer.
So, there are three types of lubricants: synthetics, semi-synthetics and mineral water. More information about these fluids can be found in the material on choosing gearbox oil. It should only be noted that the first option is the most expensive, but the most effective. It is not recommended to use it only in devices with high output. After all, the viscosity of the liquid is such that a slight violation of the seal leads to a leak. As a result, you will need to constantly monitor the level in the system and top up.
Mineral oil is the cheapest option and is often used in cars with high mileage, since the viscosity of this material is low and even significant damage to seals or oil seals will not lead to significant losses of oil from the system.
The best of all options is the third type of product - semi-synthetics. Semi-synthetics are affordable for all motorists and are an excellent solution for lubricating a unit such as axles. There are a lot of lubricant manufacturers, so choosing the optimal product is an important feature. So, these units can be filled with oils from the following manufacturers:
- Castrol Syntrax Long Life 75W90;
- GT Hypoid Synt 75W90;
- Zic G-F Top 75W-85.
The best option is to fill the axles of an SUV with synthetic oil. But it should be taken into account that the serviceability of all seals must be at a high level. Otherwise, the poured expensive oil will spill onto the asphalt and then the gears will jam. Controlling the lubricating fluid in axles is quite problematic, since the units do not have a special level to check the fluid volume. If you do not notice leaks in time, you can pay serious expenses for bridge repairs.
When is the replacement carried out?
Having found out which oil is best to pour into the axles of an SUV, you should figure out when it is necessary to begin the replacement process. The manufacturer recommends replacing lubricant in axles every 40 thousand kilometers. Changing the oil in UAZ Patriot axles is not particularly difficult, so after such runs, you can pay attention to good types of oils. But here the question arises: what volume does the front and rear gearbox have and how much fluid is needed to fill them? The volume of the rear axle of the UAZ Patriot SUV is 1.3 liters. The volume of the front axle is slightly larger and is 1.4 liters.
On a new car, it is recommended to change the oil after 10-15 thousand kilometers, because you never know what the manufacturer could have filled the axles with. Therefore, we fill the gearbox with oil for the first time after 15-20 thousand km, and the next time after 40,000 km.
Replacement in the front axle
In conclusion, it remains to find out what the process of replacing lubricant on the rear and front axles is. So let's start from the front:
- We install the car on the inspection hole and carry out the process of draining the waste. This only needs to be done when the system is preheated. To do this, you should drive the car for 15-20 minutes, and then start replacing the lubricant on both the front and rear axles.
- To unscrew the drain plug you will need a 12" hex wrench. With its help, the plug is unscrewed and the waste is drained into a previously prepared container. The photo below shows the location of the front axle drain plug.
- In order for the waste to drain faster, it is necessary to unscrew the filler plug, located slightly higher, above the drain.
- After draining the waste, you should screw in the drain plug, having previously cleaned it of dirt and dust.
- New oil is added using a technical or medical syringe. After this, screw in the plug and complete the replacement.
As you can see, the process is not particularly difficult, and every car owner can perform such procedures.
Replacing the lubricant on the rear gearbox is performed in a similar way, so it makes no sense to consider this process.
In the material, we examined all the questions regarding changing the oil in the axles of the UAZ Patriot SUV. We can sum it up by noting the importance of periodically changing the oil in SUV gearboxes. Otherwise, each car owner can imagine how this could end. Therefore, it is not always correct to choose expensive oil that may remain on the asphalt.
You can check your BMR and if you need to reduce it!
The UAZ Patriot is used for driving both on asphalt and off-road. Oil must be added to UAZ Patriot axles after the vehicle has traveled a certain distance recommended by the manufacturer. This will prevent rapid wear of transmission components.
Why is an oil change necessary?
The UAZ Patriot car has a 4x4 wheel arrangement. When driving, torque from the power unit to the wheel mechanisms is transmitted through the axles. The rear axle is constantly engaged, the front axle is connected if necessary.
The bridges are equipped with gearboxes that reduce torque. When driving a car, the gears of the gearboxes constantly rotate and are subjected to high loads.
Lubrication in the bridge mechanism performs two functions:
- Reducing friction between rotating parts. This extends the service life of components;
- Cooling. Rotating parts with good sliding heat up less. Thanks to this, the high-strength metal from which the components are made does not lose its properties.
Which oil to choose for replacement
During operation of the UAZ Patriot, the parts of the front and rear axles wear out. Chips that appear during wear enter the lubricant. This leads to deterioration in the quality of the lubricant. Chips getting into rotating mechanisms can cause them to jam. It is necessary to change the oil regularly.
ATTENTION: When driving aggressively, it is necessary to change the lubricant in the axles more often than stated in the operating manual.
Some car owners are wondering what kind of oil to pour into UAZ Patriot axles? The manufacturer recommends using gear oil with a viscosity of 75W/90. This lubricant will increase the service life of parts.
Regardless of the manufacturer, there are three types of gear oil:
- Synthetic. It is of high quality. When using high-quality synthetic oil, wear on transmission parts is minimal. The lubricant has high fluidity. This requires complete sealing of the transmission components. The disadvantage is the high cost of the lubricant;
- Semi-synthetic. Has high characteristics at an average cost;
- Mineral. Has the lowest cost.
IMPORTANT: To prevent breakdowns, you must choose a high-quality lubricant.
When to change the oil
According to the recommendation of the plant, new oil is poured into the UAZ Patriot axles every 40 thousand mileage. The first replacement is carried out after passing 15 - 20 thousand kilometers. This is due to the fact that the rotating parts are not ground in. A large amount of chips gets into the lubricant. This leads to a deterioration in its quality. You can also read about.
HELP: Wear of oil seals and seals can lead to oil leakage or water entering the axle when driving off-road.
Changing the oil in the front axle of the UAZ Patriot
According to the manufacturer's recommendation, it is necessary to replace the heated lubricant. To do this you need to drive 4–6 kilometers. Warm grease has a thinner consistency and flows out of the drain hole faster. At the end of the movement, the lubricant is replaced as follows:
- Install the UAZ Patriot on a pit, lift or overpass. The site must be level, without a side slope;
- Immobilize the vehicle. To do this, shoes are installed under the wheels;
- Prepare a container for collecting waste material. The container volume must be at least 2 liters. To facilitate the process, it is necessary to select a container with a large neck;
- Unscrew the filler plug. This is necessary to supply air to the bridge cavity. If there is insufficient air in the cavity, a vacuum is formed. The plug is located below the middle of the crankcase;
- Unscrew the drain plug. It is located at the bottom of the crankcase. The plug is unscrewed counterclockwise. To open, a 12 mm hexagon is required;
- Clean the plugs from oil accumulations, dirt and metal shavings;
- Screw in the drain plug until it stops;
- Fill with new lubricant. The filler neck is located at the top. You need to fill in the lubricant using a specialized syringe;
- Screw the filler cap until it stops.
INTERESTING: To improve sealing, some owners apply a layer of heat-resistant sealant to the drain plug.
Changing the oil in the rear axle of the UAZ Patriot
The procedure for changing the lubricant for the rear axle differs only in the amount of fluid poured. To replace:
- Place the car on the pit;
- Clean the drain and filler plugs with a wire brush;
- Using a 12 mm hexagon, unscrew the filler plug;
- Open the drain hole, having previously placed a container underneath to collect the waste liquid;
- Drain the used oil;
- Clean the internal surfaces of the plugs from metal shavings. A rag is used for this;
- Close the drain hole with a plug;
- Using a specialized device, pour new lubricant into the crankcase;
- Close the filler hole with a plug.
IMPORTANT: After completing the procedure, you must wipe off the grease from the outside of the crankcase. A dry surface will allow you to detect leaks in time during vehicle operation.
After the process, it is necessary to check the functionality of the breathers.
When heated, the liquid in the crankcase expands, displacing the air mass. A malfunction of the breather can lead to failure of oil seals or seals.
Amount of liquid to be filled
When pouring oil into the axles of a UAZ Patriot, you need to know the crankcase volume. The liquid is poured to the bottom edge of the filler neck. The UAZ manufacturer indicates in the operating manual the volumes of the front and rear axles. They are:
- For the rear axle – 1300 ml;
- More fluid is placed in the front axle. Its volume is 1400 ml.
REFERENCE: Some owners of UAZ Patriot cars note that real figures exceed the volumes specified by the manufacturer.
Equipment and materials
To change the oil in the axles of a UAZ vehicle, the following equipment and materials are required:
- Wire brush. Necessary for cleaning plugs from dust, dirt and oil deposits;
- Container for collecting liquid. The container must be of sufficient volume with a wide neck. A cut plastic canister or other container will do;
- Hexagon. A tool designed to open plugs. Supplied by the manufacturer with the vehicle;
- Rags. Used to clean the inside of corks. Use a rag to wipe away oil spills after the procedure;
- Transmission lubricant. Oil of the required viscosity is used;
- A specialized syringe or other device designed to inject liquid;
- Lamp or lantern. Used to illuminate the workplace.
Safety precautions when carrying out work independently
When performing the procedure, you must follow safety rules. To prevent the vehicle from moving spontaneously, anti-roll devices are installed under the wheels.
Before work, you need to prepare your work clothes:
- Glasses. It is necessary to work in safety glasses. They prevent transmission lube and dirt from getting into your eyes;
- Gloves. When the plug is unscrewed, the liquid pouring out of the crankcase gets on your hands. It is necessary to wear long rubberized gloves;
The fluid drained from the crankcase is at a high temperature. To avoid burns when draining the oil, a person should be kept at a distance from the drain hole. The container for collecting waste fluid should be kept as close to the crankcase as possible. When unscrewing the plug, you must hold it firmly. Failure to follow this rule may result in the plug falling into the container containing the waste liquid.
From the above it follows that changing the oil in the axles of a Patriot car is a procedure that can be performed by a person with minimal technical knowledge. Replacement is carried out at intervals specified by the manufacturer.
On the eve of the cold weather, I decided to do a small TO. Having studied the experience of the comrades, I went to buy Castrol 75v140, but as always happens, at the last moment I was led by the experience of one of my friends who sells oil. As a result, bridges were purchased 
to the distribution box
The rear axle oil was leaking black, with a clear sign of silver, the skin on the fingers after rubbing shone with small grains
on the magnet of the drain plug there are clumps of dispersion metal, on the filler there is a yellow suspension, the consistency is closer to plasticine
About 1.1 liters of oil drained, 1.3 liters went in to the top for filling
Front axle, black oil, no metal impurities were noticed
but there was some metal dispersion on the magnetic plug
the filler is clean. About 1.1 liters of oil drained, 1.4 liters filled to the brim
The oil drained from the transfer case was black and blue in color, with a clear tint of dark green, in general I described it as best I could, it was impossible to take a photo, it was dark, I didn’t measure the volume (later), but there was a slight overflow, a little could have been drained through the filler.
There are obvious pieces of metal on the plug
It turned out to be very convenient to pour Castrol from a bottle, it has a spout. The purchased syringe, by the end of work, is covered in oil and periodically leaks under the piston.
I don't recommend it.
When changing the oil in the gearbox, I was a little discouraged by the black color of the drained oil.
I still thought that everything would be ok in the box, later I was a little upset because of the presence of silver in it, although it was more likely closer to aluminum powder. Here are the clots removed from the drain plug.
the filler plug is pristinely clean, the drain plug is magnetic in the sour cream-plasticine mass, but the type is closer to a suspension than to shavings
The volume of drained oil is exactly 2 liters!
Without further ado, I took ZIC G-FF 75-85 GL4 as a replacement
I filled in 2.5 liters according to the manual.
Added Mileage 32,500 after changing the oil all around - I regret that I didn’t do this 10-15 thousand ago. The machine worked differently, some noises, which I initially considered to be a design feature of the car, disappeared.

Oil in axles and gearbox/gearbox - logbook of UAZ Patriot 2016 on DRIVE2
The entry is more for myself. I changed the oil in the axles and gearbox/gearbox at 2950 km.
Ravenol VSG 75W-90 axles. About 3 liters for both axles. Ravenol MTF-1 75W-85 transmission/gearbox. Taking into account small losses when filling (the syringe leaks anyway) 5 liters for 2 units.
How I chose. There are a lot of arguments (about DEXRON, fake oil, etc.). I didn’t see any harsh argumentation (IMHO). Other arguments are lengthy arguments. Therefore, I decided to pour what was written in the service book. Why, for example, not ZIC. While I was looking, ZIC is China, Ravenol is Germany. It’s not that I have a bad attitude towards China...
Drained. From bridges and the RK - gray slurry. There are shavings on the traffic jams (mostly on the rear axle), but IMHO, within normal limits, considering that the car has just been run-in. From the gearbox it's just dark oil.
Why did I change it? I wasn’t sure what, in general, was poured in there and how much (it felt like much less came out of the box than fit into it).
It feels like the front axle has stopped humming, or at least the humming has become much less.
The gear knob has become softer. 1, 2, back - exactly. The synchronizer began to feel 3 less. In short, it became softer :)
Now I’m at peace with 30 thousand for what’s in my units.
Z.Y. You definitely need to install protection on the RK - the wires stick out in all directions (he's a scribe), there's nothing to do to pull them out. Today I wanted to implement it too - parts.uaz.ru did not deliver the order (another story. Uservice+ was very surprised that in the store they can be indicated as a pickup point :))
Z.Y.Y. At least on my car the bottom/frame, etc. are very well processed... no traces of rye. There is a layer of coating.

How to change the oil in UAZ Patriot transmission units - axles, transfer case and gearbox
UAZ Patriot is one of the most popular SUVs on Russian roads. It was promoted to a leadership position in sales not only by its more affordable price compared to foreign analogues, but also by its excellent cross-country ability, which is relevant for domestic operating conditions. The car also deserves attention due to its excellent maintainability, unpretentiousness and ease of maintenance, which allows consumers to carry out simple technical tasks at home.
How to change the oil in the axle and transfer case of a UAZ Patriot. Transmission units of an SUV, to some extent even more than similar units of other vehicles, require regular and timely maintenance, since the vehicle is often operated in difficult and extreme conditions. In this article, we will look at how often it is necessary to fill oil into the axles of a UAZ Patriot, how to replace the transmission lubricant on your own, and which fluid is most effective for the axles and transfer case of an SUV.
When is replacement necessary?
The frequency of oil changes in each transmission unit is regulated by the manufacturer in the user manual. For cars that have just left the assembly line, the first change of transmission fluids should be performed no later than after five thousand kilometers traveled. Such a short interval is explained by the fact that after assembly, new structural parts are rubbed against each other during the running-in procedure, during which there is a possibility of the formation of small metal particles, the presence of which can negatively affect the operating life of the components and the machine.
Further changes of the emulsion in the gearbox, transfer case and axles are regulated by the manufacturer at intervals after every thirty thousand vehicle miles. It should be understood that the interval between procedures may vary depending on how high-quality the product is poured into the transmission, as well as on the operating conditions of the vehicle.
Which oil should you choose?
It's no secret that the declared characteristics of a car in terms of cross-country ability, controllability and reliability are guaranteed only if the car owner follows the manufacturer's recommendations for operation and maintenance of the vehicle. Filling with low-quality emulsion is the first and main factor that can affect the operational life of machine parts.
Accordingly, it is necessary to decide what kind of oil to pour into the Patriot’s axles, gearbox and transfer case, guided by the manufacturer’s recommendations stated in the instructions:
- To fill the transfer case housing, it is necessary to purchase a transmission product with a viscosity criterion according to SAE 75W90, corresponding to API class GL-3.
- To perform the task in the front and rear axles of the UAZ Patriot, it is recommended to use fluids that meet the operating requirements of API category GL-5, according to SAE, viscosity grade 75W
- The gearbox is filled with lubricant that meets the SAE 75W85 standard and the API GL-4 standard.
In practice, from an economic point of view, it is not practical to buy three different types of transmission fluid, especially since the products are sold in containers with a volume of one liter or more - there will be significant residues that can spoil while waiting for the next service. Car owners are advised to use identical fluids with a viscosity of 75W90 and an API class of GL-4 for all transmission components, which have proven themselves to be the most effective during operation in Patriot units.
As for the brand of lubricating fluid, it is also worth paying attention to the manufacturer’s tolerances, which recommends pouring products from ZIK and Hanval Incorporated with the specified viscosity and specification. However, the buyer can choose a product from any well-known manufacturer, taking into account the requirements for the technological properties of the product.
Refueling volumes
Having decided on the type of product required, the consumer, in order to buy it in sufficient quantities, needs to know how much oil in the UAZ Patriot will be required for a complete replacement. According to the vehicle instructions, the transmission units will require the following amount of fluid:
- The vehicle's axles will require a total of 2.7 liters of lubricant - 1.4 and 1.3 liters for the front and rear axles, respectively.
- The oil volume in the transfer case, according to the manual, is 0.7 liters.
- The volume of emulsion in the gearbox is 2.5 liters.
Accordingly, if you buy individual fluid for each of the components, then you will need to buy a liter of lubricant for the transfer case, and three liters of lubricant for the gearbox and axles. When deciding to fill with identical fluid for all UAZ Patriot transmission units, you will need to purchase six liters of oil.
Procedure
The procedure for replacing lubricant in Patriot transmission units is not particularly complicated, however, it requires patience and attentiveness from the performer. To complete the work in full, you will need to drain the used fluid from each of the system components one by one, replacing it with new lubricant. For this purpose, it is first necessary to prepare new oil in a volume sufficient for replacement, a set of car keys, containers for used fluid, as well as work clothes.
The task of replacing fluid in transmission units is carried out from the bottom of the car. In service centers, special lifts are used to ensure unhindered access to drain openings; at home, it will be enough to drive the vehicle onto a pit or overpass.
Before performing the operation, it is important to drive an SUV for about ten kilometers so that the lubricant in the system warms up to operating temperature. Under the influence of temperatures, it will become liquid and merge from the aggregates faster and better. Further measures are carried out in accordance with the work schedule for each transmission unit.
Changing the oil in axles
The procedures for changing the oil in UAZ Patriot axles do not differ in execution technology, so let’s look at the procedure for implementing the tasks using the rear axle as an example. In practice, you can successfully perform a replacement by following simple instructions from the car manufacturer:
The oil change in the front axle of a UAZ Patriot is carried out in a similar way, with the only difference being that the oil filler and drain plugs must be looked for on the front axle housing. The front axle housing will contain no more than 1.4 liters of lubricant. At this point, the procedure for replacing the lubricant in UAZ Patriot axles can be considered successfully completed. Then you can move on to changing the oil in the transfer case and gearbox.
Changing the lubricant in the transfer case
The methodology for changing the oil in the transfer case of a UAZ Patriot is practically no different from the procedure for changing transmission fluid in axles. To perform the procedure, you will need to find the drain and filler holes, clean the surfaces one by one from dirt accumulations and unscrew the filler plug. Then the waste is removed into the prepared container through the drain opening. Once the liquid has drained, you need to tighten the drain plug and fill the oil through the filling opening using a technical syringe to the limit, which will be a little more than two and a half liters in volume.
Along with changing the oil in the axles and transfer case, it is recommended to change the lubricant in the gearbox, the technology of which is the same as in previous situations. When pouring new oil into the gearbox, the level should be monitored using a special dipstick with which the car is equipped. After filling and running in the car, you will need to recheck the level in the gearbox; you may need to top up the oil to normal.
After replacing the lubricant in all transmission components, you need to start the car and drive it for several kilometers, after which you drive it onto the overpass again and check all the joints for fluid leaks, and if necessary, tighten the plugs more tightly.
Let's sum it up
UAZ Patriot transmission units are designed to operate in aggressive operating conditions, and therefore are characterized by increased endurance. Despite this, their operational period directly depends on the owner’s compliance with the regulations for their maintenance. Irregular oil changes or completely ignoring them can cause vehicle failure, reducing its handling, maneuverability and safety on the road.
It is not difficult to carry out routine maintenance of axles, transfer cases and gearboxes at home, but it is advisable to replace the transmission oil in all components, which, on the one hand, will allow you not to get confused about the timing of re-replacement, and on the other hand, will extend the life of the car. And, most importantly, do not skimp on the quality of the lubricant; the operational period of components, assemblies and the vehicle as a whole depends on this.

Changing the oil in axles. - logbook UAZ Patriot Baby Patrick 2008 on DRIVE2
And so, I got to the bridges, or rather to changing the oil in them. I also needed to find out the reason for the large idle rotation of the flange, about 90 degrees, of the front axle in which the self-block is installed. The previous owners had no idea what company it was. I drove the car into a warm box, unscrewed the drain and filler plugs on the front axle and saw what was inside.
