Clunking on passenger side rear only on really bumpy road

Hi there, just had this clunk start up that's driving me insane.

 

So I live in a really bumpy street, and it clunks a lot when I get home. Highway, turns, even pothole bumps I don't hear it.

 

The sound to me was my rear sway bar end link, as it has happened before. Lucky me, I have a spare one in the trunk and I replaced it.

 

No dice, it did not dissappear. I went under the car today and bench pressed/rattled and shook the rear bar, trunk etc and couldn't find anything loose. I thought the next thing would be a loose bushing or mount on the sway bar itself. I got a tiny noise out of it, but I would expect "some" noise/movement on the rear bar itself. I couldn't visually see it move, just a faint clunk.

 

Any other ideas what to look for? No heat shields or loose mufflers here, it is definitely a clunk/rattle in the rear right as I got a passenger to confirm for me.

 

Just.. bothering me I can't pinpoint the new noise...

I had a similar clunking with an aftermarket RSB installed. It was the sway bar bushings, though I couldn't feel a lot of play in them either. Replaced them with poly, grease-able bushings and the problem is now gone for me.

hmm easy enough to change, which ones did you get?

I needed 22mm for my RSB... I considered Whiteline, but wound up finding some Energy Suspension ones locally, which worked fine and included a new mounting bracket, etc. Hard to believe, but I actually got them from Autozone for ~20 bucks. Seems like a decent product. The rubber bushings that they replaced were in pretty rough shape, so it was $20 well spent. Hope it fixes your clunk too.

interesting..I did just read about putting Teflon tape in.. might give it a quick shot just to check if the sound goes away...

So I went outside today and took the bushings off, Teflon taped and back on... I think it might be fine, which means I will see how long they last ( Teflon) until I have to buy new bushings.

Clunk gone?

Will find out tomorrow, just did one pass down my block and it is better for sure.

I had the same issue, got new tires and the clunking sound went away! weird, don't know what the hell was happening.

It sure would be nice to get a real answer on this issue. This is an issue that I have been trying to deal with as well with my 05 gt. There are quite a few seemingly endless threads on the clunk issue. I have read everything from its normal, deal with it to failing strut bearings. If bushings fix it then good for you, but please for the love of flat 4s someone post a conclusion and make it a sticky!

Sorry for not updating.. one month and counting, clunk is still give via the Teflon tape to the bushing. I'll definitely buy a new Set of bushings next time, although the Teflon tape was basically a free fix..

Thanks man! Looks like I'll be doing bushings next weekend.

Did the same thing for my Perrin 22 mm RSB. No more clunking sound. I now love going over crappy roads.

 

Your bushings probably need to be replaced. Make sure you get the correct size. Ask me how I know.

I wonder if the oem bushings are soy based

I would like a description on this clunk. cause I'm getting a noise back there and I thought it was the passenger side shock. Which I looked at and it's squirting grease. But I'm wondering if it's the sway bar.
