Title: Suspension problem
Post by: Jimbob on 19 December 2011, 12:07:00
Went over a pothole today, and was then met with a nasty clunk and rattling from the back of the car.

Nothing to see underneath...

Checked the shock mounting points, and the passenger side rear upper shock mount was dented :y

The amount of shock absorber poking though seems far too much..

other side for comparrison

Inside I have these parts,

underneath I have this,

which looking on the guides here, and EPC, I dont seem to be missing anything  ???

Whats gone wrong?  how do I fix it?
formost in my mind is the shock 'threaded bar part' has pulled out from the main shock and is now too long?  is this even possible?

Shocks are 18 months old, genuine GM MV6 ones.

HELP!!!!


(ive had a clunk, I think from the front of the car for some time, which may, or may not be related)

looks like its missing a collar off the lower part that should stop it pushing up through the rubber mount

Whatever acts as a stop at the bottom of the threaded section has opened up/fell off/gone missing ???

Have you looked at the aperture in the floor James,to see if the shock has been pushed up through it ?
Lower washer No.6 - cant see it in your pic. :-\

from your pics of bits i can only see one of the 2 no6 washers, the bottom one is missing allowing the top of strut to push up through the rubber

yes, top of 8/9 sits snugglly in the opening....but with loads of 'bar' not just the threaded end.


Hmmmmm maybe 6 I am missing, should that sit at the very start of the threaded section?  That looks like it could be it?

Whoever changed the shock at some point has ommited the big washer,and hitting a big bump has allowed the rubber bush to be pushed up into the inside of the car.
Worth having a look at the order of assembly on the other side ?

looks like trip to local breakers for you to find said washer

id be checking that the other side is fitted too, or you could find that you end up with same problem in near future

Ahhh, Breakers in Sandycroft by any chance?  May be about if you fancy a cuppa?  have a few commitments, but may be about.

I replaced em about 18 months ago....I would have noticed, it has failed somehow, sure of it.
Title: Re: Suspension problem

Agreed, the lower load spreading washer is missing.

Cant see how they could fail as its not like there is any turning motion that could wear them and both to fail the same way (e.g. both sides) is lottery win territory.

Post by: adey2 on 19 December 2011, 13:17:42
thats why i said check both sides, if they forgot to fit on one side it could of been left out other side too, im also not sure if youd tell if wasnt there unless removed as rubber covers it in compression

No, nor me, but something let go spectacularly today...and cant see how I wouldnt have noticed before now.

Car has had a lot of use, and some quite heavy loads, yet was empty today when it happened.

nah im picking it up from a home adress, bloke broke his car, figured for 50 quid it worth the run as my miggy on lpg too so not a bomb in fuel costs, only thing i can think about your prob is the washer sheared in two when issue happened

It must be something like that, it cant have survived like that for 18 months!

I assume the shock is moving ok across its full stroke?
