Disassembly
Remove the protective cover using a flat-blade screwdriver.
Suspension Spring Compressor
Using tool J38402, A20, compress the suspension spring until almost all spring force is removed from the strut.
Loosen the nut on the strut rod.

Disposal of suspension struts
Extend the telescopic strut rod fully.

Warning: The gas released is harmless, but care should be taken when disposing of the resulting metal chips.
Checking the technical condition
Check the upper strut mount for wear or damage.
Check rubber parts for damage or deterioration of material properties.
Check the suspension spring for shrinkage and looseness.
Checking the operation of the telescopic stand
Check the telescopic stand for excessive rigidity or unusual noise during operation.
Assembly
Installing the lower spring support cup cushion
