Introduction

It is necessary to put the car on a jack stand and plan for it to be immobilized for several days. Don't forget that quality tools (or even new ones) are necessary for certain steps! The operation is not very complex but it is necessary to do things rigorously because the suspension is a very important element for the road behavior of the vehicle.

  1. 
Open the hood

Locate the shock domes

Locate the 3 screws + nuts on the shock dome
    • Open the hood

    • Locate the shock domes

    • Locate the cap on the shock head

  2. 
Using a flathead screwdriver, remove the shock absorber cap

Do not unscrew anything!

Put the car on a jack stand for your safety

Remove the wheels
  4. 
Look behind the brake disc to see the screws to be removed.

  5. 
Place a candle under the hub to relieve the stress on the screws

We loosen the screws from the previous step

For the screw and its nut you need a socket wrench and an open-end wrench.

  6. 
Unscrew the screws and the nut

Put the parts in a box with a label

It is always better to replace the removed screws with new ones.

Remove the ABS sensor cable and brake hose from the shock absorber by hand

  8. 
Unlock but above all DO NOT UNSCREW the nut of the shock absorber rod!

It is possible that the nut turns in a vacuum, in reality it turns with the rod in the shock absorber.

At this point, you need a 22 mm (very thin) ring spanner to turn the nut and a 6 mm Allen key to lock the rod. (photo 3)

    • Photo 3 is an example of how to UNLOCK the rod nut on the shock absorber.

  9. 
You can unscrew the 3 nuts (13 socket) from the shock absorber dome

Be careful, you have to hold the shock absorber from underneath because it will fall.

Be careful of the ABS that goes around the shock absorber. You have to remove the shock absorber without damaging it.

Check that the center distance of the 3 studs is the same

You can also check it before disassembly directly on the dome.

Take the maximum possible amplitude to set up the compressors (several turns)

Place the spring compressor claws on the coils (top and bottom)

    • Put the safety devices (depending on the model)

  12. 
Some springs have a red marking that indicates the location to put the compressor

By tightening by hand (for positioning), check that the 2 compressors are perfectly opposite each other in relation to the spring axis.

Compress the spring by tightening the compressors in turn.

    • Compress the spring by tightening the compressors in turn.

    • (I used 2 ratchets to go faster and avoid compressing one side more than the other)

    • Compress the spring until it no longer applies force to the cup and therefore to the shock absorber stop.

  13. 
This time we need to completely unscrew the nut that we loosened in step 8.

Use a socket with a pair of pliers or vise grips to lock the nut. Then an Allen key to turn the rod

Do not put your face above the shock absorber!

Once the nut is removed you can remove the shock absorber stop

Be careful not to lose the washers (yellow arrows)

Remove the spring but without putting your fingers between the coils

    • The cup washer is not present on all E36s

  15. 
Replace the stops and protective plastics with new ones.

Reassembly in reverse order

Have the nut screwed onto the rod before starting to loosen the compressors

Place the spring securely in the notch of the shock absorber with its rubber before loosening the compressors.

Conclusion

The operation is not very complicated but it can be very dangerous or even fatal if you do not do things correctly. Again, use tools in good condition.

Hello, is there a direction in which to assemble the cups because there is an arrow so how are they oriented? Thank you.

Good morning,

I think the exploded view of step 14 should tell you. But the cup turns freely on its axis since it is mounted on a bearing.

Thanks for the tutorial.

Just a question. I have a 96 e36 320 ia coupe. M52 engine. I wanted to know how to find the reference on the shock absorbers. Indeed on various sites there are various types of shock absorbers. For sports chassis etc.

Yours sincerely,

Good morning,

Unfortunately I will not be able to provide you with any information, sorry :/
