Notes About Adjustment Work On The Spring Struts

NOTE: Spring strut comes out of the damper tube
  • PASM (damping force adjustment) does not function

→ 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 -3-  for adjusting the height of the vehicle. The height-adjusting nut -3-  is prevented from turning by the lock nut -2-  .

The height-adjusting nut -3-  and the grooved nut -2-  are not available as spare parts (these are supplied with replacement dampers).

  1. 2  - Lock nut (grooved nut)
  2. 3  - Height-adjusting nut/lower concave washer (grooved nut)

  4. X  - Pre-set dimension for production: 268.5 mm (plus/minus 1 mm). The dimension may be different for the prescribed vehicle height. If the vibration damper is to be replaced, the existing dimension must be set on the new vibration damper.
