Steering Gear: Adjustments

Power assisted steering box (ZF), adjusting

Notes: Two technicians are required when adjusting. Adjust with engine switched off.

- Raise vehicle on hoist.
- Wheels in straight- ahead position.

- By turning the steering wheel back and forth (about 30° to center axis) a knocking noise will be heard if there is excessive play.





- The second technician carefully screws the adjustment screw (arrow) into the cover until the knocking noise can no longer be heard inside the vehicle.
- Complete a road test ensuring that when maneuvering or negotiating corners the steering self - centers without sticking.





- Secure adjusting nut to stop it turning by making a center punch mark in the collar of the steering box housing.
