My impreza gc8 sti has a creaking/knock like sound coming from rear of car when going over gradients and incline/declines.

Sound seems to have started since i installed whiteline rear arb mounts, Whiteline rear drop links and a cusco rear arb.

I have ensured all bolts are torqued correctly but the sound remains.

When disconnecting the arb from the drop links the sound stops - removing the possibility of a rear suspension top hat being the culprit.

Should i be looking at replacing the rear drop links - despite them looking ok?

Also what is the difference between the whiteline rear drop links KLC26 and W23480?

 

How well did you grease the arb bushes

 

Yeah mate quite a lot! Just strange the noise is still there. Reckon it is worth re greasing them?

 

Have you checked your outrigger bushings.

 

is the correct bar & d/links for your application??

 

Yep you have to watch you get the right ones

 

Everything fits as you would expect and I bought the stuff from a member on here, It was a cusco 20mm rear arb and a set of W23480 silver whiteline droplinks

I suspect it is the drop links and will test another set and go from there

Thanks!

 

I bought new ball jointed Whiteline droplinks last year, and on one the joint was all loose, the other was stiff as f**k. Not well made, and now rusting .
