Replace screws each time they are removed. Only use original spare parts (microencapsulated screws). Threads in cross members, screw theads and washers must be clean and free of grease. Always fit the screws evenly until the fastening clamps are level with the cross member before tightening the screws.

Break off M 6 and M 8 breakaway screws after carrying out a functional and visual inspection of all relevant components.

Replace setscrews and locknuts each time they are removed. Tightening torque also applies to cars with airbag (steering wheel with sliding section and universal joint at steering box).
