Correct the rear articulation angle ( 3)

Corresponding shims are available as a replacement part for articulation angle correction at the rear axle center assembly.

The shims are available with a hole eccentricity of 1 mm to 4 mm. 1 mm corresponds to a change in the articulation angle of approx. 0.2° to 0.3°. The eccentricity measurement is marked on the top of the shim.

Shown on shims with a hole eccentricity of 4 mm and in the correct installation position

3 Support rear axle center assembly with transmission jack and transmission platform.
4 Detach bolts (51a) and nuts (51c) from transverse bridge (51).
5 Remove shims (51b).
6 Install the appropriate shims (51b) according to the type of correction.

Ensure that the shims (51b) are correctly positioned, see diagram. All the shims installed must have the same eccentric hole arrangement.
