Top Mount Knock
 

Hi,

WRX STi Spec D 07/07 24k miles.

I'm pretty sure that I can here my N/S/R top mount knocking, and there was an advisory on the last MOT (3/5/12) @ 21 k miles.

The advisory note says "Nearside rear (inner inner strut) shock absorber has a slightly worn shock absorber pivot [2.7.4]

So, with that said, does the tester mean top mount? I'm not entirely sure what I can hear knocking, but I can hear something, and I'm sure it's suspension related.

Any ideas?!

Many thanks,

Matt

The shocks on this model are prone to knocking,some grease may help for a while but it will return

Ok, cool. But I would rather fix the problem straight away permanently. Do you know what part that is likely to need replacement?

Usually a new strut

Join the club pal,the suspensions rubbish on these things, you can only replace is via Subaru , or it's the dreaded coilovers. You can strip, regrease and fit a grease nipple, that's the way forward I think.

I don't think a grease nipple & packing the strut with grease is the way forward!

The Bilstein struts on the RB320, suffered the same knocking as all the OE Newage strut. However, Bilstein re-worked the strut adding a 'third' bearing, which has worked & i've not heard of a re-worked strut failing AT ALL.
Simon from Chevron Motorsport works direct with Bilstein and is the man to speak to!!

Are the Bilstein's compatible with my OE springs / mounts etc?
Where would a third bearing go?

Not sure, but I doubt it! As the RB320 is lowered compared to the standard Type Uk STi.
The 'third bearing' is a modification the inner workings of the strut itself. That's about as technical as I can get!!

Understood. Thank you.
