HELP PLEASE !!! Rear Shocker Replacement.


HJM

Recommended Posts

Have followed the excellent pictorial guides to remove the rear shock absorber, but I am struggling to actually remove the existing Bilstein shocker which is on a standard spring.

 

I have used spring compressor clamps and the three bolts in the boot have been undone..

 

When I knocked out and removed the bottom securing bolt from the 'U' shaped bracket at the end of the shocker,the bracket simply slid down the rear suspension arm (outwards) and I can't get the hub assembly to drop at all.

 

I have tried jacking the other side of the car but to no affect.

 

Any ideas how to get the hub assembly to drop and hence allow the shocker to be removed ???

 

Thanks

Have you got the entire rear of the car in the air? If you have the opposite wheel on the ground, the anti roll bar (assuming you still have the links in place) will be pushing this side upwards.

 

I found that I didn't need to undo the ARB links like it says in the service manual. However I did need to put my entire weight on the hub to force it down far enough to move the bottom of the damper over the suspension arm. There seems to be a knack to getting the damper at the right angle for removal. Try also compressing the damper with your hands as you move it over, it will have a natural tendancy to extend even with the spring compressed.

 

Maybe try some cushioning between you and the hub / brake disk while you're pushing it down - I ended up with some very interesting marks on my chest! :blink:

Thanks for the advice :)

 

Yes car was jacked up both sides.

 

ARB links still in place - tried to undo one as the whole hub assembly looks like its being prevented from dropping by it.

 

However after a few turns of the nut the extended washer lug (other side of bracket)which I assume is designed to prevent rotation (like having spanners either end of a bolt) just keeps turning - tried putting a spanner and then a screwdriver under it to stop the rotation, but to no avail :( How do you undo these damn things ??!?!?!?

 

Sounds like I need to get a mate to come and help me and then we can attack it with some brute force and ignorance.

 

Anyone else got any other suggestions / experiences ???

Shouldn't need to to touch ARBs or anything like that.. As has been said..

 

There are the three nuts on top by the turret and then a bolt that connects the damper to the lower arms, pull that out. Put a bit of weight on the hub and the entire damper and spring assembly should pull out.

Is it not far easier to just remove the assembly and take it apart out of the car?

 

Thats what i did.

 

May have to resort to that, but the bolts/nuts undone so far were hard work as obviously not touched for years.

 

If I remove the whole lot - I reckon it could take a very long time !!!

Are the spring clamps tight enough? My Tein coilovers had plenty room for removal once I had the clamps on then but then again they are probably shorter than your ones.

 

Got the clamps turned down a fair way - enough to get the top of the spring of the underside of the arch by a few millimetres - I could try more turns.

As above, I have already undone and removed all of these and did try pushing down with some weight on the hub.

 

Either springing back, although I felt virtually no movement or not exerting enough pressure.

 

Hence, think its best to get a mate to help push down the hub and I can hopefully extract the shocker and spring.

:yeahthat:

Its easy.

the worst thing you can do is split the damper whilst its on the car, will be a right pain getting it off, its only a 15minute job to take it off as one whole piece.

Its much easier with two people, one to put some weight on the hub, and the other to coax the damper out.

I'm not following you here.

 

To remove the rear strut i

 

1. Jacked up the side i wanted to remove (to keep the ARB going in the direction i wanted it to)

 

2. Removed the wheel but put the nuts back on to hold the disc in place

 

2. loosened off the top 3 nuts (kept them on though).

 

3. Removed the pin holding the bottom of the strut

 

4. Pushed down on the disc/hub assy until the strut cleared the location then moved it a little to the side so that it missed (the nuts still being attached at the top will mean the strut doesn't go with the assy but they must be loose enough so that you can move the strut to the side.

 

5. Take the weight off of the disc/hub assy being careful of where the strut rests.

 

6. Loosen off the top 3 nuts

 

7. Remove strut

 

In total you will have 4 nuts and 1 pin washer.

 

I didn't need to loosen anything else to do the rear.

Oh yeah,

 

To strip the strut once out of the car i

 

1. Loosened off the main nut holding the strut to the topmount (Bit of a pain to get it to loosen without rotating). Make sure you only loosen it a turn or so.

 

2. Compressed the spring evenly on both sides till i could rotate the spring in the strut (means no pressure is on the topmount)

 

3. Loosen off the topmount nut.

 

4. Remove spring & gently ease off spring compressors and your done...

 

or just swap the unit out while in situ.

Thanks for the replies, but I have done all the necessary above.

 

Definitely looks like I need someone to help me to push down the hub whilst I get in there and remove the shock/spring/top mount assembly in one go.

 

I think overall my problem is that the hub will not freely drop, unlike other cars which look sick on a post lift with all four wheels dropping downwards.

 

I had a sneaking suspicion that it all looked too easy in the guides and hence I thought I could do it on my own - obviously a big mistake.

 

Should have the necessary assistance on sunday so fingers crossed we can make the car surrender to our will :)

 

Thanks

I did the rears on my own, the fronts i needed someone to move the strut away. With the rears i put my full weight on the hub assy to lever it down and then reach under to move it.

 

Did you not say you jacked up both sides? If so this is where you are going wrong IMO.

Cheers guys for all the info/experiences.

 

Makes me feel pretty confident I should be able to sort this with some assistance.

 

Although a mechanic I spoke to this morning suggested jacking both sides and releasing both shockers.

 

He also said best not to use spring compressors for removal and just use them to assist installation of the new shocker away from the car.

 

Fingers crossed I get it sorted sunday - looks like I'll be watching the F1 highlights.
