Steering Shaft Coupler: Service and Repair

Remove/Install Steering Coupling






1 Fully extend or pull out adjustable steering column

NOTE: Required to separate the steering coupling (25).

2 Deactivate easy entry/exit feature

CAUTION: Deactivate the easy entry/exit feature otherwise the windshield may be damaged if the holding device is installed.

3 Turn steering wheel to center position (front wheels in straight-ahead position) and secure with holding device

CAUTION: The steering wheel must not be turned with the steering coupling (25) detached otherwise the clock spring contact will be destroyed.

5 Detach steering coupling (25) from lower steering shaft (80a) by unscrewing bolt (25a)
6 Pull lower steering shaft (80a) up and out of steering coupling (25)

CAUTION: Do not use force (hammer blows, excessive leverage) as the lower steering shaft (80a) is sensitive to lateral forces.

NOTE: Installation: Insert bottom steering shaft (80a) fully into the steering coupling (25); pay attention to the studs of the steering coupling (25)and groove of the lower steering shaft (80a) (arrows).

7 Unscrew nut with bolt (25b) from steering coupling (25)

CAUTION: Installation: Replace self-locking nut.

8 Carefully pull steering coupling (25) off control valve of rack-and-pinion steering (23)

CAUTION: Do not use force (hammer blows, excessive leverage) as the control valve has a predetermined fracture point. If necessary, widen the clamping groove slightly using a screwdriver.

NOTE: Installation: Turn rack-and-pinion steering to center position and fit steering coupling (25).

9 Pull locking plate (25f) off steering coupling while lifting lug using a suitable tool

CAUTION: Installation: Replace locking plate (25f) with self-locking nut. Push up locking plate (25f) until the lug engages in the steering coupling (25).
