    Information 

    When replacing the air spring, always replace the boot/bellows.

    If the rolling piston slips out of the outer guide during disassembly, it must be correctly positioned again when assembling.

    • When sliding in the rolling piston, the roller must lie evenly between the outer guide and rolling piston (roll fold). 
  6. Push bellows downward and secure in this position (2nd worker required!). Grasp the rolling piston and remove it upward from the shock absorber by slightly turning to the left/right.
