If you still have the clunck after fixing all that, my money is for sure on the upper control arms.

 

Please let me know what it ends up being, I have this same problem and dont wanna spend all that money searching for it.

 

Thanks for the input...that was kind of my guess as well...but i have good news!!!!

Today after coming home from work, i kept thinking what else could it be??? didn't want to keep throwing money at the GS.....then I remembered reading about another GS owner with same clunking issue, he fixed it due to loose sway bar bolts.....jacked up the car....checked the swaybar screws..and BINGO!!! they were loose ....after tighting all of them...Car is back to Normal...car feels great again......OP double check your sway bolts... hopfully its an easy fix like mine...GL...

 

I love fixes like that!!! Sweet!!

 

Is there anyway for you to show me where these screws are located? pics perhaps :-) ? Were you able to tell they were loose by wiggling the sway links because my mechanic checked them for play but didnt check the screws

 

Yeah ill take some pics for you tomorrow...but if you have a jack, just jack up your car..if you know how a swaybar looks you can't miss it.... had to tighten four 12mm bolts...

When I was underneath my car, I tried wiggling the sway bar...but didn't move at all...once I thouched the bolts...I was able to turn them...hopfuly yours is an easy fix like mine.


Had to replace my lbj's and tie rods for piece of mine though...

 

Indeed!!! Me too

 

Below you will see the nut and bolt to tighten, circled in red. Make sure you tighten both sides. GL

 

thanks bro your the best, but btw were yours just loose on their own or did you ever adjust or change the sway links, because ive never heard of a bolt coming loose on a well built car by itself.

 

Np.....well about a month ago I had new front shocks installed..I remember having them tightend after install...I drove about a week and car was perfect...but then one night on the freeway I kept taking turns at high speeds...the next day the clunking started... so I'm assumming the shocks/springs or combo of other things settled in and made them loose..

Just check them...might just be that.

 

I just watched my mechanic try to tighten the nuts/bolts. They didn't budge. I do need struts though I did the bounce test where you push them down and they bounced at least once before they stopped. Could the worn struts be the clunking noise? Because its not the sway bolts

 

i have the same problem but my sway bar looks firm

 

what kind of suspension are you running and what is your ride height? maybe your UCAs are hitting the strut tower. mine was hitting once in a while due to my worn shocks. mine only happened on speedbumps on the downward movement from the bump.

 

Since its not your sway bar bolts... as others have mentioned.. check your uca's..
