Risk of damage to electric lines

→ Protect electric lines when removing and installing the spring strut.

→ Do not lift/transport the spring strut/vibration damper at the electric lines.

→ Do not damage electric lines when transporting, unpacking, storing or disassembling and assembling the spring strut.

The spring strut has a thread and a height-adjusting nut -12- for adjusting the ride-height of the vehicle. The height-adjusting nut -12- is prevented from turning by the lock nut -11- .

The thread also comes with an adjusting nut (grooved nut) -13- for installation (correct position of spring strut in the wheel carrier).

The height-adjusting nut -12- and the grooved nuts -11 and 13- are not available as spare parts (these are supplied with replacement dampers).

11 - Lock nut (grooved nut)
12 - Height-adjusting nut (grooved nut)
