Correct articulation angle on rear axle differential

1	Nut
2	Eccentric disk

P41.10-A014-11

 The change in inclination of the rear axle differential not only changes the articulation angle at the rear of the rear propeller shaft relative to the rear axle differential ( K5), but also the articulation angle at the front of the rear propeller shaft relative to the rear of the rear propeller shaft ( K4). Therefore a complete check measurement must always be carried out after an articulation angle correction.

1	Unscrew nut (1) and remove eccentric disk (2).

2	Mount new eccentric disk (2) onto screw with required eccentricity, screw on nut (1) and tighten  .

 Eccentric disks are available in millimeter graduations of 1 to 4 mm. The eccentricity dimension is applied to the eccentric disks, the eccentric disks only have one possible installation position.

 If the rear axle differential is raised at the front suspension by 1 mm, then:
 the articulation angle at the rear of the rear propeller shaft relative to the rear axle differential ( K5) becomes smaller by approx. 0.2°;
 and the articulation angle at the front of the rear propeller shaft relative to the rear of the rear propeller shaft ( K4) is increased by approx. 0.07°.

 If the rear axle differential is lowered at the front suspension by 1 mm, then:
 the articulation angle at the rear of the rear propeller shaft relative to the rear axle differential ( K5) becomes larger by approx. 0.2°;
 and the articulation angle at the front of the rear propeller shaft relative to the rear of the rear propeller shaft ( K4) is reduced by approx. 0.07°.
