Adjustment of a convergence of forward wheels
1. Wheel position with positive toe-in, viewed from above. In this case, the value -B- is in front.
2. Before adjusting the toe, loosen the wire ties on the rubber cuffs so that they do not twist. Loosen the locknut on the tie rod end and adjust the tie rod by turning the hexagon.
3. When adjusting the toe, it should be taken into account that the distribution of the toe on the left and right should be the same, which means that the steering rods must be turned out by the same amount. Maximum difference in length: 3 mm.
4. Tighten the locknuts of the steering rods with a force 40 Nm. Secure the rubber cuff with a wire tie.
Front camber adjustment
1. If the camber is out of range, under certain circumstances it can be adjusted by rotating the shock absorber mounting plate. To do this, loosen the 4 upper fastening nuts (before 9/89 issue: 2 nuts) shock absorber and turn the mounting plate 180°, the marked mark will be on the outside. Camber will then change to +29'. Screw the fixing plate to the required tightening torque, see chapter Suspension and steering system.
Adjustment of a convergence of back wheels
Cars up to 9/89, issue. and models "station wagon"
1. The convergence of the rear wheels is adjusted by rotating the two eccentrics on the rear transverse arm. After adjustment, measure the distance from the eccentric supports to the wheel rim. Repeat the measurement on the other wheel. The deviation between the right and left sides can be a maximum of 3 mm.
Note. After adjustment, tighten the eccentric bolts by hand and lower the vehicle onto the wheels. Only then finally tighten the bolts to 110 Nm.
Vehicles since 10/89, except models "station wagon"
2. Adjust the toe-in by turning the threaded rod on the rear transverse arm, loosening the lock nut beforehand. One turn of the thread changes the toe by 11.3 mm. Evenly distribute the adjustment between the two wheels. After adjustment, tighten the locknuts 60 Nm.
