WM, 432537 Disassembling And Assembling Rear Spring Strut (Air Springs): Information: Overview

Information

As of a mileage of 200, 000 km (125, 000 miles), it is recommended that the air springs be replaced on both sides of the axle if there is damage to one air spring.
If the vibration dampers are leaking, replace the complete air-spring strut. The oil from the vibration damper can damage the convoluted air bellows.
When depressurized, the air spring must not be twisted. There is a danger that the convoluted air bellows inside the air spring will be damaged by bending or folding, thereby significantly reducing its service life.

NOTE: The greatest possible care and cleanliness, as well as perfect tools are important requirements for carrying out perfect repairs on air-spring struts. The general and basic rules of safety apply. These are specifically listed here again for repairing air-spring struts.

Thoroughly clean the connection points and their surroundings before loosening them.

Do not use fibre-shedding cloths.

Do not take spare parts out of the packaging until right before installation.

Only use lubricants that have part numbers.

Carefully cover open components or close them if repair work will not be carried out immediately.

Do not use an impact bolter.

Observe correct tightening torques.
