Strange noise. Suspension related? HELP!
Hi guys,
recently changed the rear shocks as they were shot on my 01 bug wrx at the same time got some Tein lowering springs fitted since then there has been a strange noise from the rear of the car. The noise only occurs if you go over any bumps or undulations in the road surface and is worse/more noticeable at slow speed. The actual sound is difficult to explain its sort of a rubbery squeal with a knocking noise I think. Have had my mechanic who did the work take a look and he is unable to locate the issue. With enough force being pushed on the rear when parked up it can be made to make the noise but when i looked couldnt locate where it was coming from. Any ideas, known causes? |
Mmm! I have that rubbery noise too on the front.
Be interesting if anyone knows... |

the bushes on droplinks/Arb may need greasing or the shocks a knocking:(
I hope the shocks not knocking as they are new. I did wonder about the Arb and drop links and the mechanic mentioned them too. Will have a look into them, is it likely that they need to be uprated or just greased? |

i did EXACTLY the same to my classic, and straight after i had the EXACTLY SAME problem, for weeks it was driving me nuts :brickwall so retraced my work to find out i had'nt tightened the nut on top of shock enough, bam prob solved, worth a try, but i did have to remove the shock to do it, dont know about newer scoobs, worth trying :thumb:

Still got this issue anyone got any other suggestions please?

Sounds like it could be bush related to me.
How much lower is the car now though? Are you sure the knocking isn't the shock hitting its bump stop? |

Got it lowered on tein spings they they lower it by 35mm?

I did have a golf gti that I lowered though and that used to make noises and squeaks from the bump stop on rough road. Scared the sh#t out of me sometimes when I hit a pothole!! :eek: |
