Clunk/rattling noise coming from the back end
 

Hi guys, I was wondering if you could help me out. Since I have had my 2004 blobeye (only a couple of months) it has always had a bit of a clunk/rattle from the back end. It is more noticeable on the passenger side but I think there is a noise on the other side as well, just nowhere near as loud.

Originally I thought it was something to do with the boot maybe as it has an STI spoiler but I suspect only the stock WRX torsion rods (boot springs whatever you want to call them). So I took the boot, hinges and rods off this weekend and took it for a drive but it was still making the noise.

I have been reading up on this problem and it seems to be fairly common on stock suspension whereby the suspensions rattles as it does not have enough grease in them but this has KW coilovers (I think V3's) on them which led me to think that maybe the top mount has gone.

I took the top mount cover off, as I already had the rear interior out to remove the boot, and they seemed OK from a visual inspection on top but are there any tests I can try to find out if it is definitely the top mounts or has anyone else had any similar issues whilst using coilovers?

Any help would be much appreciated.

My bugeye 02 wagon clunks enough to feel it on a turn thats a bit more than a light turn. In the wet it breaks away into a slide, not ideal for a road car! Ive (probably wrongly) assumed it was a mod by the prev owner, (the boot had a full on fluro lights ICE install) who I thought was a boy racer who liked to raz it up. The back end feels like it has AWS and 'flows' around corners in the dry. Is that normal?
Any suggestions anyone?

My blob eye also clunks n rattles on any uneven ground when going slowly thort was exhaust but have rattled exhaust and leant rubbing on anything, any ideas ?

Check the rear anti roll bar and mounts, ive just had to change my arb due to the bar corroding and becoming too thin for the bush to hold it properly, ive now fitted a whiteline bar and its all sorted.

Rear strut top mounts

give this a try. It worked for me.
