- Park the vehicle on a level surface and measure the rear wheel alignment.
- Before measurement, the elements and parts of the rear wheel suspension must be brought into normal technical condition.
Convergence
- If the toe value does not match the nominal value, adjust it as follows:
- Before adjusting the toe, adjust the camber.
- Adjust a convergence of back wheels by rotation of an adjusting bolt - (mounting bolt on the inside of the suspension adjusting arm) (pic. 14.48).
Pic. 14.48. Arrangement of a bolt of adjustment of a convergence of back wheels
Left-hand side: clockwise rotation of the bolt increases toe-in.
Right side: turning the bolt clockwise will decrease the toe.
One scale division corresponds to a movement of approximately 2.6 mm, which is equivalent to a toe angle of one wheel of 0°16'.
Collapse
Camber: - 0°40'±30'
Difference between left and right wheels: no more than 30'
Note. On vehicles with aluminum rims, measure the camber on each wheel using special tool MB991004, tightening it to 180 Nm.
- If the rear camber is out of specification, adjust as follows.
- Disconnect the adjusting arm from the rear suspension trailing arm.
- Adjust the camber by turning the adjusting bolt (lower arm bolt to rear cross member) (pic. 14.49).
Pic. 14.49. Rear camber bolt location
Left wheel: clockwise rotation increases camber.
Right wheel: clockwise rotation reduces camber.
One scale division is approximately equal to 0°14'
- Tighten the adjusting arm to trailing arm bolts to 34 Nm (pic. 14.50).

- After adjusting the camber, be sure to adjust the toe of the rear wheels.
