Introduction

Working on struts is very dangerous and even fatal. If you are a beginner, hesitant or do not have quality equipment, do not touch anything.

There are 2 types of shock absorbers: oil and gas.

If your new shock absorbers are oil-filled and the rod is pushed in, this is normal, but if they are gas-filled, the rod must be raised as far as possible.

In this tutorial, the new shock absorbers are gas-filled.

The operation was performed on the right side.

  1. 
Stabilizer bar link

Shock absorber retaining bolt in the spindle

ABS sensor retaining plate
    • Stabilizer bar link

    • Shock absorber retaining bolt in the spindle

    • ABS sensor retaining plate

    • Bras transversal

    • Hunting shot

    • Steering rod

  2. 
Using a 17mm socket remove the nut

then the ABS sensor plate

then uncouple the stabilizer bar link.
    • Using a 17mm socket remove the nut

    • then the ABS sensor plate

    • then uncouple the stabilizer bar link.

    • Using an 18mm socket and an 18mm ring spanner remove the bolt

    • then the brake hose plate

    • Using a wire brush, clean the shock absorber as best you can to make it easier to remove.

    • Using a small flat head screwdriver, remove the dirt and then spray with lubricant.

  3. 
Lock the threaded rod with a T40 torx socket then unscrew the nut with a 21mm ring spanner.

  4. 
Place wooden wedges under the brake disc now because the first few hammer blows will cause the spindle to slip quickly.

Place a screwdriver in the slot in the spindle and push it in far enough to make it easier to slide the shock absorber in.

Gently tap the top of the rocket with the hammer.

    • Place a screwdriver in the slot in the spindle and push it in far enough to make it easier to slide the shock absorber in.

    • Gently tap the top of the rocket with the hammer.

    • Try to hold the rocket as much as possible with your free hand.

    • Place the rocket on the blocks.

    • Make sure the whole thing is stable

    • The assembly must not rest on the brake hose!!!

  5. 
Using a 13mm ring spanner, remove the 3 nuts.
    • Using a 13mm ring spanner, remove the 3 nuts.

    • With your free hand, hold the strut which is only held by these 3 nuts.

    • Deceiver

  6. 
Much more stable and safe than "hand" compressors, you still have to be careful. Although the spring will be well engaged in the claws, there is always a risk that once under pressure it will "jump".

    • Claw for the strut

    • Guide rail with locking screw

    • Claws for the spring

    • Spring retaining claws. They slide and lock into the rail to fit the spring.

    • Pressure management pedals

    • Pressure pedal

    • Pedal to release pressure

  7. 
Compress the spring until the cup is free.

If your shocks are old, chances are you have no other options than the impact wrench with a 21mm long socket because a normal socket or a curved ring wrench will not fit.
    • Compress the spring until the cup is free.

    • If your shocks are old, chances are you have no other options than the impact wrench with a 21mm long socket because a normal socket or a curved ring wrench will not fit.

    • If you are using a ratchet wrench with a through socket you will need a long socket or an extension. The problem is that you will not have enough space to place a 6mm Allen key other than along its length and therefore not enough grip to block the rod.

    • Then you remove the cup and decompress the spring.

  8. 
Due to their horizontal storage, air bubbles may form in the gas circuit, so they must be purged before installation.

Lower the shock absorber rod to the stop and let it rise several times to bleed it.

    • Upper spring sole

    • Spring plate

    • Support plate

    • Dust cover that fits under the stop.

    • Seal washer that is placed on the stop.
