Front suspension clunk on bumps

str8shot · 07-19-2012, 09:20 AM

Getting a new clunk from my front end on moderate size bumps. Like pulling into the apron for my driveway.

I've got AST 5000 coilovers, hotchkis sway bar with turner drop links, and vorshlag camber plates.

Any idea where to start trouble shooting? Everything is tight as far as I can tell...

loose sway bar end links....

Or an upside down sway bar...make sure it goes over the suspension arms and not under.

Might be ball joints. Could be time to get M3 control arms.

It could be anything...when did the noise start? Can you hear the noise if you were to have someone push down on the front-end of the vehicle? I would suspect the endlinks and maybe the bearing on the Vorshlag plates if you have a bunch of miles on them.

+1 had the same problem.. even if you tighten them they eventually loosen.. use the stock ones and the sound will be gone.

I had the same problem. It was fixed with vorshlag heim joint replacement. Also i would suggest to go back to stock end links,

Having the clunking problem right now and have H&R coilovers. What were repair costs on this issue??

it doesn't cost anything to tighten something yourself....
