Shock absorber problems

I've heard several owners of STi's (2003-2005) have had problems with 'knocking' rear shock absorbers.

Some got replaced under warranty.

Has anybody done this and got any explanation of his dealer on the what's and why's ?

I've also read on a forum that you need to ask to swap them with specific shocks rather than with the same items.

Reason I ask is that my scoob has this problem now rear left AND right :evil: . Plus it starts to behave in a weird way (it's as if there is no suspension anymore at the rear). It goes in for a service this week and I want to get this sorted.

Getting it done here is always tricky as: it's probably the only STi the dealer ever seen, warranty needs to be claimed back from Subaru UK and he's 60 miles from where I live... Plus there is a bit of a language barrier. :shock:

Any advise from other people is also welcome !

Thanks ! :help:

This sounds like the struts are sticking inside the damper unit. Try lifting the rear of the car at the rear wheel arch and see if the car sits back down again. If it sticks up then that is your answer.

Should be replaced under warranty if not expired.

Thanks !!

:up:

I'll go and try that straight away. I must admit I've had a few times that the car suddenly moves down when coming to a halt. As if the strut is stuck inside the damper.

Keep you posted.

You're welcome mate. Mine has been doing it for a frew months. It's only noticeable at very slow speed - but doesn't hinder me on track at Goodwood/ Nurburgring, etc

I really need to get it sorted but other than the noise and feel when you stop/ start it has no other negative effect. I really want to go the whole hog and get some AST adjustables

Cheers

Nice ! You often do trackwork ?

I'm a bit sceptical about taking the scoob to the track though as it's mainly a rally car and not really adapted to tracks (understeer...).

I DO love to blast it through forest roads in winter though, 110mph sideways in between snowwalls... :wbounce:

They didn't notice anything wrong with the shocks.

But as the knocking is terrible, and they checked everything else, they put in a claim to swap them under warranty anyway.

Will use the opportunity to fit the Prodrive spring kit at the same time.

... and mudflaps...

Problem solved !

:jump

They replaced the shocks under warranty this week. When they came off, we checked them and the strut could be moved left and right in its housing for a few mm, plus it would cause a knocking sound.

Tried to move struts on the new shocks left and right but didn't move at all :up:

The mechanic assumed some dirt got into the shock absorber. Which wouldn't be surprising looking at the state of the seals.

Yes !

I put an update on that too in the other tread ("experiences with STi Prodrive spring kit" or something).

As said, Not as good as i thought as the car loses its very sharp reactions on tarmac. It does however become more controleable and nimble. So should hopefully cure the understeer problem on ice and be more fun this winter !
