Camber settings affect vehicle handling and tire wear.
Increased positive camber will cause premature wear on the outside of the tire and cause increased wear on the suspension components.
Increased negative camber will cause premature wear on the inside of the tire and will also cause increased wear on the suspension components.
Camber that differs by one degree or more on both sides of the vehicle causes the vehicle to pull to the side with more positive camber.
The angle of the longitudinal inclination of the axis of rotation of the wheel (caster or castor) is positive if the top attachment point of the pivot axis is shifted back relative to the bottom attachment point. The angle is negative if the upper point of attachment of the pivot axis is shifted forward relative to the lower point of its attachment.
The angle of the longitudinal inclination of the axis of rotation of the wheel affects the handling of the car, but does not lead to an increase in tire wear of the car. The caster angle of the wheel axis depends on the height of the vehicle, so it is important to ensure that the height of the body corresponds to the value set by the factory design. Overloading the vehicle or weakening the rear suspension springs affects the caster angle of the wheel axis. If the rear of the car is lower than the front, the front suspension shifts towards positive caster, and vice versa.
If the positive caster angle is too low, the steering will become too sensitive at high speeds, and the ability to return the wheels to a straight line when exiting a corner may be reduced. If one of the wheels has a larger caster angle than the other, that wheel will pull toward the center of the vehicle, causing the vehicle to steer to the side with a more positive caster angle.
Front camber adjustment (GNB)
1. Place the vehicle on the leveling stand in an appropriate manner.
Note. Use new fasteners, but do not fully tighten to allow movement.
2. Replace camber adjustment fasteners (1) on the swivel.
3. Replace upper ball joint mount (2) on the swivel.
4. Adjust the camber of the front wheels to the required value (see section «Service data and specification» at the end of the chapter).
5. Tighten, but do not fully tighten, the camber adjustment nut on the front knuckle.
6. Check the camber again and correct if necessary.
7. While holding the camber adjustment bolt, tighten the new nut (1) on the steering knuckle with a torque of 70 Nm, after which it is sequentially tightened by another 45°and 15°.
8. Tighten the fasteners of the upper ball joint (2) on the steering knuckle with a torque of 115 Nm, then sequentially tighten another 45°and 15°.
9. Repeat the procedure on the second front wheel.
Rear camber adjustment
1. Loosen the fastening of the upper arm of the rear suspension to the subframe until mutual movement occurs.
2. Turning the fastening of the upper arm of the rear suspension in the required direction, adjust the camber to the required value (see section «Service data and specification» at the end of the chapter).
Note. The rear camber is changed by turning a cam nut in the car's subframe.
3. Tighten, but do not completely tighten the upper suspension arm to the subframe.
4. Check the camber again and correct if necessary.
5. While holding the nut, tighten the new rear suspension upper arm bolt to 150 Nm.
6. Repeat the procedure for the second rear wheel.
