Help & Advice

• Loosen but do not unscrew the top center nut (l).

• Unscrew the lower fixing (2).

• Unscrew the upper mounting (3) and remove the shock absorber assembly.

• Compress the suspension spring to remove any pressure on the center nut (l). Take the greatest number of turns between the hooks of the spring compressor.

• Remove the central nut (1) and all the other parts from the upper part of the shock absorber, noting their positions (including the compressed spring).

• Check the condition of the dismantled parts and change the defective parts, in particular the anti-bottoming stop.

In the case of a cartridge shock absorber: unscrew the worn nut (4) and remove the cartridge.

Don't forget to prime by pulling the shock and compressing it vertically a few times.

1- For cartridge shock absorbers:

• 1-1 Thoroughly clean the inside of the tube and pour approximately 50 ml of engine oil into it.

  Note : This dose of oil will be trapped between the cartridge and the tube to allow proper cooling of the shock absorber.

• 1-2 Insert the replacement cartridge in the strut and if it comes with a centering cup (5), fit it (Fig3).

  Tighten the cartridge nut to the torque recommended by the vehicle manufacturer.

2- Completely remove the rod and refit the suspension spring with the upper attachment, the dust cover, the anti-bottoming stopper and the new upper central nut.

After replacing the front MacPherson struts, check the adjustment of the front axle.
