Default Just got back from Subi service, no help from them

I posted my issue in the Suspension thread but didn't get to much help so I made an appointment with Subaru. I just picked up an 06 WRX and its ridding on Cobb springs. it definitely has the rear clunk which I thought was the struts. Subaru looked at them and there fine. Other then suggesting new springs they didn't really help. I guess i could but i doubt that will fix it. Now I have used the search here and there are allot of possible solutions. I just would like to hear from someone who really knows first hand what i cant do to fix this.

Sorry for the long story, just need some help.

Thanks

check to make sure your endlinks are tight... it could also be the rear diff smacking around.... when does your car make the clunk....

When they had the car on the lift i was under there with them and everything looked really good. I felt the end links by hand and there weren't loose but idk if thats a fair test. The clunk happens on any bump or uneven pavement. it sounds almost like a hollow clunk and its coming from the right rear. Again there suggestions were maybe somethings not seated right or the springs are hitting something. But nothing looked out of place. All i know is its driving me nuts.

My guess would be rear diff issues. WIth my girlfriends 2000 legacy GT the CV joint is either bad or needs grease because when turning at a slow rate of speed, it clunks around

Can you open the trunk and kneel in it and bounce around to simulate the clunk? Then my next question is do you have a friend that can pin point it or do the bouncing?

At the dealer this morning we were bouncing the back and the no clunk. i was thinking maybe side to side but i doubt it. I talked to the tech line at Cobb and they gave me a few suggestions. Gonna check all the bolts and if thats not it I'm just going to have to take the strut out and see what i find. Sucks.

i had a clunk from my right rear , when i brought it to the dealer they said it was normal, but it sure didnt sound normal. i made a pest of myself and they replaced the strut under warrantee and that solved the problem. things i also checked were the spare tire, the wing mounts , and anything els back there that could work loose and clunk aroundwhen i hit a bump

I had/have a similar problem. Your exhaust might be hitting the rear sway bar. It sounds similar to the strut clunk but a tad different. I've been through both of those scenarios

if you have a stock exhaust, then maybe that's not the problem.
i tightened the piss out of my endlinks on my cobb rear sway bar when i first installed it, and i started getting a 'clunk' problem and my mechanic buddy said it was a bad strut. tightened the sway bar on the passenger side a hair more and haven't heard it since.

just my .02 cents

Did you take the tech for a ride in the car with you, and point out the noise? Often times a good tech will hear a noise, and know right where to look (then again, this is the Subaru dealership we're talkin about here). IMO, if it's only over bumps, it has to be in the suspension.. possibly a broken/ worn strut.. or something with the new springs (not seated right.. too short for struts). When/ how did the noise start?.... was it right after you installed the springs, or some other event?

Yes i took the tech for a ride and he heard it right away. He put it on the lift and said the struts are fine, no leaks and are still perfectly firm. Other then scratching his head he didn't really know. Yeah it only happens over bumps or uneven pavement where the suspension is moving. After a day or reading and talking to people this weekends project is...

Check the end links on the sway bar.
Check sway bar clearance.
Check the springs to see if the powder coating is coming off indicating the springs are rubbing.
Check top nut assembly.
Check the top hat .
Take strut out and check for damages.
Disconnect sway bar and test drive.
Disconnect strut bar and test drive.

Oh and install new Borla hush exhaust

If that doesn't fix it I give up.
