Wheel Alignment





Overview
Before checking the wheel alignment, the height of the car must be measured. See Measuring car height before checking wheel geometry.
1. Set up the equipment for 4-wheel alignment and follow the instructions for using it.
2. Check rear wheel alignment against the values in the Rear wheel alignment tables and adjust as necessary.
3. Check front wheel alignment against the values in the Front wheel alignment tables and adjust as necessary.

Adjustment of rear wheel toe-in
1. Raise the car on a 4-pillar lift so that the wheels and suspension are under load.
2. Fixate the longitudinal links with Fixture 89 96 795





3. Slacken the bolts on the body attachment bracket for one of the longitudinal links.
4. Using sleeve, 89 96 811 move the bracket outwards or inwards. Move it inwards to increase toe-in.
Check the alignment.
5. Tighten the bolts.
Tightening torque 90 Nm + 30° (70 ft. lbs. + 30°)
6. Repeat points 3-5 on the other side of the car.
7. Apply anticorrosion agent to the body.
8. Continue with Adjustment of front wheel toe-in.

Adjustment of front wheel toe-in
1. Start with Adjustment of rear wheel toe-in if this has not been done.
2. Secure the steering wheel in the straight-ahead position.





3. Undo the locknut on the track rod.
4. Rotate the track rod clockwise to reduce the toe angle or anticlockwise to increase the toe angle. Read off the value and compare it with Wheel alignment.

Important: Make sure that the dust excluder (gaiter) does not rotate when the track rod is turned.

5. Tighten the locknut.
Tightening torque 70 Nm (55 ft. lbs.)





6. Check the length of the track rods by measuring the distance (A) between the locknut and the groove in the track rod at the dust excluder. This distance should not exceed 149 mm.
Maximum permitted difference in distance between right and left-hand sides is 7 mm.
7. Use a corrosion protection agent on the track-rod threads after tightening.
