Disassembling front spring strut

WARNING: Preloaded or pressurized components

Risk of squashing or bruising

→ Do not reach into the danger area.

→ Relieve the tension on components before starting work.

→ Secure components to prevent them from loosening suddenly.

NOTE:

Shock absorbers must always be replaced in pairs as soon as at least one of the following preconditions is met:

→ Mileage: 25, 000 km (15, 500 mls)
→ Age: 2 Jahre

NOTE:

Observe the correct allocation (engine variant/chassis variant) when installing new coil springs and/or shock absorbers .
Springs must only be replaced in pairs .

NOTE:

The front spring strut is disassembled and assembled using the tool stationary spring tensioning device WE 1610 .

Before inserting the spring strut, the tool stationary spring tensioning device WE 1610 must be set up and adjusted in accordance with the operating instructions provided by the manufacturer.

Insert spring strut in the stationary spring tensioning device WE 1610 . → Spring strut in spring tensioning device (conventional spring strut shown)

Applies only to conventional spring strut:
Align mounting saddle chamfer concentrically with respect to the mounting plate.

Applies only to PASM spring strut:

Spring strut alignment (conventional)

Insert threaded bolts -1- of the spring strut into the bores -2- on the mounting plate.

Spring strut alignment (PASM)
Pre-tension spring strut using drive nut -1- until the tension on the piston rod is relieved.

Tensioning spring strut
Unscrew nut on piston rod → Unscrewing nut on piston rod . Use socket-wrench insert 3353 on PASM spring struts.

Unscrewing nut on piston rod
Relieve all tension on the spring strut using drive nut -1- (there must be no tension on the coil spring!).
Remove all components from the piston rod.
