Correct wheel alignment angles are one of the most important factors ensuring normal controllability, stability and stability of the car when driving straight and when cornering. The optimal suspension geometry parameters for each model are set at the design stage. The specified values of wheel alignment angles are subject to change and require periodic adjustment due to natural wear of components and elements of the chassis or after suspension repairs. Also, the angles should be adjusted when making changes to the car’s suspension, for example when lifting.
Types of basic car wheel alignment angles
| Parameter | Car axle | Is the parameter adjustable for UAZ? | What does it affect? |
|---|---|---|---|
| Camber Angle | Front Rear |
No | Cornering stability Premature tire wear |
| Wheel Toe Angle (Toe) | Front Rear |
Yes | Straight-line stability Premature tire wear |
| Lateral steering angle (KPI) | Front | No | |
| Longitudinal angle of inclination of the axis of rotation (Caster) | Front | No | Vehicle stabilization while driving |
| Scrub Radius | Front | No | Vehicle stability when braking Vehicle stabilization while driving |
Story
Where did it all start?
The car was the direct successor of the cart. Remember what it was called at the dawn of motorization? - Horseless carriage. It was the design of the cart that formed the basis of the first cars.
However, a car differs from a cart in that it is not pulled, but drives itself. What will happen if such a cart is not pulled, but pushed, and at the same time one wheel hits a small obstacle? For example, on a pebble or a pothole on the road?
In this case, the system leaves a stable state (linear motion) - the front axle sharp unfolds. This happens due to the large shoulder break-in.
How to deal with this? The first thought is to make the running-in arm equal to zero with separate steering axes for each wheel. Something like this.
Let's say. Then no brick or hole in the road will be able to turn the wheel around its turning axis. By the way, this design introduced a longitudinal inclination of the wheel turning axis (castor), which at that time was already used in bicycle designs. However, as cars became heavier and their tires wider, this solution began to cause problems. The fact is that it is very difficult for the driver to turn the wheel of such a car in place or at low speed due to the increased weight of the car and the profile width of its tires. There were no power steering systems at that time, and therefore the designers decided to make the running shoulder not zero, but a length of about 25% of the width of the tire profile.
Now, when hitting an obstacle, the turning moment, compared to the cart, has decreased by several orders of magnitude, and the effort when turning the wheel has become several times less than with zero leverage, because Now, when turning, the wheel does not rotate around the center of the tire contact patch, but rolls, albeit along a small radius.
But if there is a shoulder, albeit a small one, each wheel tends to turn outward even when driving on a flat road (without stones and holes). To reduce the turning moment caused by the presence of the running shoulder, the wheels are not installed straight, but at a certain angle. This one is called an angle wheel alignment. Now the turning moment is compensated by the toe-in of the wheels, but the wheels themselves move, as they say, like a plow.
Now is the time wheel camber. If the “plowing” wheel is tilted outward, then due to the elastic deformation of the tire, the wheel in the contact patch with the road will take the shape of a strongly truncated cone that will roll in an arc. Now, in fact, we do not have cylinder wheels “going plow”, but two truncated cones. And due to the fact that these “cones” have both toe and camber, their treadmills are directed directly.
But now, after turning the steering wheel, the wheels “don’t want” to return to a straight position, and in general, all the time you have to “catch” this very straight position. Positive castor helps little here. What to do?
This problem was solved simply - we tilted the steering axis of the wheel. in the transverse plane(angle β). Now when you turn the wheel, the front of the car will rise up. The steering wheel will become a little heavier, but when the car moves, the wheels will tend to take a straight position, as they say, automatically.
Over time, car speeds increased and it was necessary dynamic stabilization- so that the wheel, at speed, returns to its original position if for some reason it deviates. To do this, we introduced the longitudinal angle of inclination of the rotation axis - caster. (piano wheel principle)
In dynamics, the wheel tends to take the most stable position, which is behind the axle.
Now, when turning, the lateral reactions of the road applied behind (thanks to the caster!) try to return the wheel to its place.
Moreover, if the car is subject to a lateral force that is not associated with turning (for example, you are driving along a slope or in a crosswind), then the caster ensures that the car turns smoothly “downhill” or “downwind” when the steering wheel is accidentally released and does not allow it to capsize.
Now about the same thing, but more formally:
Camber is the angle formed by the middle plane of the wheel and the vertical passing through the point of intersection of the middle plane of the wheel and the supporting surface. There are positive and negative camber:
positive (+) - when the top of the wheel is tilted outward (away from the car body)
negative (-)- when the top of the wheel is tilted inward (toward the car body)
Structurally camber is formed by the position of the hub unit and provides maximum contact patch area tires with the road. With a double-wishbone independent suspension, the hub position is determined by the upper and lower wishbones. In MacPherson-type suspension, the formation of the camber angle is influenced by the lower arm and the shock absorber strut. Deviation of camber angle values from the norm affects the car as follows:
+ good car stability in corners
- wheel grip deteriorates during straight-line movement
- increased wear on the inside of the tire
Positive angle too large:
+ good wheel grip
- stability in corners deteriorates
- increased wear on the outside of the tire
For UAZ vehicles, the camber angle is set rigidly and is:
For UAZ-452 And UAZ-469: 1°30+-15"
for UAZ Patriot and UAZ Hunter with axles like Spicer: 1°
Wheel alignment- the angle between the longitudinal axis of the car and the plane of rotation of the wheel. Can also be defined as the difference in distances between the front and rear flanges of the wheel rims (in the figure this is the value A minus B). Thus, toe can be measured in degrees or millimeters.
There are total and individual convergence. Individual toe is calculated separately for each wheel. This is the deviation of the plane of its rotation from the longitudinal axis of symmetry of the car. Total toe is calculated as the sum of the individual toe angles of the left and right wheels of one axle. The total toe-in in millimeters is determined similarly.
With a positive toe-in, the wheels are mutually turned inward in the direction of movement, with a negative toe-out, outward.
Deviation of toe angle values from the norm affects the car as follows:
Too much negative angle:
- maintaining the trajectory of movement deteriorates
- increased tire wear on the inside
- acute reaction of the car to steering
Positive angle too large:
- maintaining the trajectory of movement deteriorates
- increased tire wear on the outside
Wheel toe-in on UAZ is adjustable and is for cars (B-A)
UAZ-452, UAZ-469: 1.5-3.0 mm. (23"+-0.8")
UAZ Patriot, UAZ Hunter with Spicer type bridges: 0.5-1.5mm(from 0°3"04" to 0°9"12")
Transverse angle of inclination of the wheel rotation axis
Transverse angle of inclination of the axis of rotation (English KPI)- the angle between the axis of rotation of the wheel and the perpendicular to the supporting surface. Thanks to this parameter, when the steering wheels are turned, the car body rises, as a result of which forces arise that tend to return the wheel to a straight position. Thus, KPI has a significant impact on the stability and stability of the vehicle when driving in a straight line. The difference in the lateral inclination angles of the right and left axles can lead to the vehicle pulling to the side with a large inclination. This effect can also manifest itself when the other wheel alignment angles correspond to the normal values.
For UAZ vehicles, the lateral inclination angle is set rigidly and is:
UAZ-452, UAZ-469B: 5°30"+- 0°30"
UAZ-469 with portal bridges: 8°
UAZ Patriot, UAZ Hunter with Spicer type bridges: 8°
Wheel axis casting angle
Longitudinal angle of inclination of the axis of rotation (English caster)- the angle between the steering axis of the wheel and the perpendicular to the supporting surface in the longitudinal plane of the car. There are positive and negative angles of longitudinal inclination of the wheel turning axis.
Positive caster contributes to the emergence of additional dynamic stabilization vehicle when driving at medium and high speeds. At the same time, low-speed steering deteriorates.
The longitudinal inclination angle of the king pin for UAZ vehicles is set rigidly.
For UAZ-452, UAZ-469, UAZ-469B: 3°+-0°30"
For UAZ Patriot, UAZ Hunter with Spicer type bridges: 5
° -1°
In addition to the above parameters, another characteristic is of great importance for the front axle - shoulder break-in. This is the distance between the point formed by the intersection of the axis of symmetry of the wheel and the supporting surface, and the point of intersection of the line of transverse inclination of the steering axis and the supporting surface. The rolling shoulder is positive if the point of intersection of the surface and the axis of rotation of the wheel lies to the right of the axis of symmetry of the wheel (zero shoulder), and negative if it is located to the left of it. If these points coincide, then the running shoulder is zero.
This parameter affects the stabilization and steering of the wheel. The optimal value for modern cars is a zero or positive break-in shoulder. The sign of the run-in shoulder is determined by the camber, the transverse inclination of the wheel turning axis and the offset of the wheel rim.
Car manufacturers do not recommend installing rims with a non-standard offset, because... this may lead to a change in the specified running-in arm to a negative value. This can seriously affect the vehicle's stability and handling.
Partially used materials from the article by Alexey Trebunskikh
To ensure stability and controllability of the car, the front wheels of the car are installed at certain angles relative to the body and suspension elements. Three parameters are subject to adjustment: toe, camber angle and caster angle.
Rice. 1. Casting angle of the wheel axis
The casting angle of the steering axis (Fig. 1) is the angle between the vertical and the line passing through the centers of rotation of the ball joint and the bearing of the upper support of the spring strut guide, in a plane parallel to the longitudinal axis of the vehicle. To increase the angle of inclination of the turning axis, the upper support of the rack, originally located as shown in photo 1, must be rotated 180° relative to the hole in the body mudguard cup (photo 2).
In this case, the longitudinal inclination angle of the turning axis will increase by 0°52" (the operating procedure is described in subsection).
Wheel camber angle (Fig. 2) is the angle between the plane of rotation of the wheel and the vertical. It is adjusted by turning the upper bolt securing the shock absorber strut to the steering knuckle (see. “Removing the spring strut guide”).
Rice. 2. Wheel camber angle
Wheel toe (Fig. 3) is the angle between the plane of rotation of the wheel and the longitudinal axis of the car. Toe can also be defined as the difference in distances between the flanges of the rims, measured from the rear and front of the wheels at the level of their centers. Toe-in is adjusted by rotating the inner tie rod by the flats when the lock nut of the outer tie rod end is released (see Fig. “Removing the outer tie rod end”).
Rice. 3. Wheel alignment
It is recommended to check and adjust the angles of the front wheels at a service station. Before making adjustments, make sure that the tire pressure is correct, the tire tread wear on the left and right wheels is approximately the same, there is no play in the hub bearings and steering elements, and the wheels are not deformed.
Checking the wheel alignment angles is mandatory if suspension components and parts that affect the values of these angles have been replaced or repaired. Due to the fact that the installation angles of the front wheels are interconnected, first of all the angle of the longitudinal inclination of the turning axis is checked and adjusted, then the camber and, lastly, the toe-in.

Answer to your question: For a car in this version, there is no technical ability to adjust the control unit. Best regards, AutoHERMES group of companies!And finally, toe-in. We are talking about the total toe (the sum of the angles between the longitudinal axis of the car and the plane that passes through the center of the right and left wheels). First for the front wheels. The advantage of positive toe is stability at high speeds, but the disadvantage is increased understeer. The advantage of negative toe is the improved reaction of the wheels to the movements of the steering wheel, and the disadvantage is the rapid wear of the rubber, the transmission of road irregularities to the steering wheel, or simply “beating”. As for the rear wheels, the situation is almost the same. If you make a negative toe-in, the car will be prone to skidding. The most optimal thing is to drive the car with zero toe-in on both axles.
The geometry of the wheels is what the driver’s life depends on. Incorrect wheel alignment of the UAZ greatly changes the vehicle's handling characteristics. Moscow, as a large city with difficult driving conditions, makes wheel alignment an even more cost-intensive problem - if the settings are incorrect, tires wear out quickly. Computer wheel alignment of UAZ, or rather modern services for diagnosing and adjusting wheel geometry, is an activity that requires high qualifications and precise equipment. Not every technical center will perform a high-quality alignment.
The workstation of a UAZ wheel alignment specialist must ensure that the vehicle is horizontal when adjusting angles and wheel alignment and that the suspension is evenly loaded. Unfortunately, the average lift always has a slight misalignment, sometimes amounting to several degrees. Is this so harmless if the suspension deflection practically does not occur during slight misalignments of the lift? No, even 1-2 degrees of “non-horizontal” lift leads to 1-2 degrees of error in measurements due to the gravitational principle of measurements of most stands. If we consider that, for example, the full tolerance for wheel camber on modern cars does not exceed 30 minutes (half a degree), then a lift error of 1-2 degrees will fatally affect the results of measurements and adjustments.
What indicates the need for a UAZ wheel alignment?
. There was a slip or the steering wheel changed its position when driving in a straight line.
. The car does not hold the road well (yaws).
- Good afternoon
UAZ Patriot 2016, wheel alignment
Vitaly: Camber alignment on 2 axles after replacing the kingpins.
Maxim: make wheel alignment.
Andrey: UAZ Patriot alignment address price
Every car owner has heard terms such as wheel alignment more than once. These terms mean the need for repairs, which may be needed at any moment. This need is due to the need to repair poor-quality road surfaces or operate the vehicle in harsh off-road conditions. Actually, the UAZ Patriot SUV is designed for such aggressive operating conditions, so every all-terrain vehicle owner needs not only to know what wheel alignment is, but also to be able to make adjustments with their own hands.
Purpose of wheel alignment
The need to check and adjust toe-in, as well as wheel camber, arises after repair work has been carried out on the chassis. You should also visit a service station after your car hits large potholes or potholes at speed, which lead to damage to the integrity of the chassis. But even if the UAZ Patriot is driven exclusively on smooth roads, then even in this case it is necessary to periodically visit a service station or adjust the wheel alignment yourself.
Another sign of poor alignment is uneven wear on the front tire tread. If you notice that the tread is eaten away on one side, then an adjustment is urgently needed.
Toe is the parameter at which the wheels are in relative position relative to each other. If this parameter is violated, an asymmetrical position of the wheels relative to each other is detected. At the same time, they are spread out in different directions, which negatively affects the car’s chassis and tires.
Special device for adjustment (ruler)
Camber and alignment are two completely different parameters, but they are carried out together at the service station. It is not difficult to find out that a UAZ Patriot SUV requires toe adjustment. To do this, you need to drive onto a flat and smooth road and let go of the steering wheel at a speed of 60-80 km/h. Moreover, if the car pulls in any direction, then adjustment is urgently required. Otherwise, untimely adjustment will result in failure of the suspension components of the UAZ Patriot. But as you know, the first to bear the brunt of such a malfunction are the tires. It all starts with quickly wearing off the treads in one or another part of the rubber. In addition, this has a negative impact on the wheel rims; their curvature is observed. To visually imagine what constitutes camber and what is toe-in, a sketch is presented below.
Camber is the angle by which the plane of the wheel deviates from the vertical. The camber on the UAZ Patriot is not adjustable - only adjustment, repair or replacement of the king pins is performed.
Self-adjustment
The camber and toe angles on the UAZ Patriot SUV can be adjusted independently at home, saving a considerable amount of money. In addition, this procedure is recommended to be performed periodically, but at least 1-2 times a year. This will save your car from serious damage and the need to purchase new tires.
So, if you have decided that you need to adjust the camber and toe of your car, then the first thing you should do is make sure that the chassis is in good working order. If there is a need to repair or replace suspension parts, then adjusting the wheel alignment angles is simply pointless.
Having determined that the chassis does not need repair, you can begin the procedure for adjusting the wheel alignment angles. First you need to find a level place where such events will be held. The UAZ Patriot SUV should be freed from excess weight and the tire pressure should be checked. This is very important, because these parameters can become incorrectly adjusted.
Using a caliper in measurements
Let's get started with adjusting wheel alignment angles and perform the following steps:
- Initially, it is necessary to set the steering wheel in a straight position, thereby aligning the wheels.
- Before adjusting the alignment, you need to make chalk marks on the inside of the wheel at the front. Marks should be placed as close to the discs as possible.
- You need to take a special bar (ruler) to measure the distance between the inner surface of the tires.
- The ruler must be rested between the two wheels at the marked points. In this case, the ruler should not touch the car parts.
- You need to record the distance on the ruler.
- Now you need to roll the car forward and measure the distance at the rear of the wheels with a ruler at the same points. In this case, the ruler should not touch the body parts and suspension.
- The readings are verified.
- When measuring, it is necessary that the distance in the front part be 1-1.5 mm less than in the back.
- If the distance between the wheels in the rear position is less than in the front position, then the tie rods need to be lengthened to equalize the values.
- If the values, on the contrary, are greater, then the rods should be shortened.
- If the deviations do not exceed 1.5 mm, then the wheel alignment can be considered complete.
Adjust the wheel toe-in on the UAZ 3303, as well as on other models 469, 452 “loaf”, etc. Just. In addition, unlike passenger cars, the UAZ does not have camber.
I’ll probably start with why it’s impossible to adjust the camber on the UAZ 3303. The fact is that this parameter is built into the design of the car itself, namely the steering knuckle.
If you have no play in the kingpins, and the hub bearings are properly tightened, then everything will be fine with this parameter.
It all started with the steering wheel sluggishly returning to its original position, but the worst thing was that the car began to scour the road. At the same time, it might not appear on level ground, but if unevenness or especially rutting appeared.
Tools
For repair you will need:
- Key to 30;
- Key to 27;

It is important! Adjustment of the toe-in of the front wheels of the UAZ 3303 is carried out at normal tire pressure. The tie rod ends must be in good working order and without play. The adjustment is to ensure that distance A in the front is less than distance B by 1.5 - 3.0 mm in the rear.
Wheel alignment is usually checked using the inner surface of the tires. But given that the lateral runout of tires can be significant, the toe may be adjusted incorrectly. Of course, it’s best to adjust on a stand, but in the past we always did it ourselves. In this case, when adjusting the toe, I take two measurements, one between the tires, the second between the disks. The difference when measuring in the second case should not exceed 1.5 - 2 mm.
Before starting the adjustment, it is necessary to prepare the rod for measurements. To do this you need a small wooden strip and a caliper. Secure it all as in the photo. I purchased an inexpensive plastic caliper for this purpose. You can do without a caliper, using a ruler, for example, by securing it with rubber bands and putting marks.
Wheel alignment is adjusted by changing the length of the steering rod. To do this, lock nuts with right and left threads are loosened in advance and the adjusting fitting is rotated, and the length of the rod is changed.
- Locknut with left-hand thread; 2. Adjustment fitting; 3. Lock nut with right-hand thread; 4. Hinge.
The car is placed on a flat surface, a measurement is taken from the front at the middle of the height of the wheels, and a dot is placed at the points of contact. Then they roll the car halfway around the circle and take another measurement from behind. The difference between them will be the wheel toe value.
To be sure that the correct alignment of the wheels on the UAZ is correct, you can repeat it at other points.
The tie rod ends must be in good condition and without play.
