I installed a set of TC UCAs a few months ago and have been trying to track down a clunking sound since. It's very annoying to hear a clunk every time I hit a bump. My friends say it's pretty loud outside too. Is there anything that can be done to quiet these things down?
At first I thought maybe it was because of running 5100 front struts w/886x springs. So I bought OME 9000 front struts. That didn't help, but did give it a much nicer ride. I also bought some Tri-Flow lubricant for the uni-balls and Super-Lube grease w/PTFE as the instructions say to use.
I then started replacing items continuing to track down this clunk. This includes LCAs (including ball joints and bushings), steering rack, and outer tie rods. These items were worn, so it wasn't wasted money, but I still have the clunk.
I removed the sway bar to eliminate that as a cause. The clunking is not as bad now, but is still there.
I had it aligned yesterday again after installing these items. The mechanic couldn't figure out where the noise was coming from either. He suspected the UCAs, but has never seen a set of TC before, so he didn't know anything about them. He assured me the LCA bolts are balls ass tight and are not moving. He also convinced me to run it with 3.6 caster, but I think it pretty much drives like a limo now, so I may have him put it back closer to 3.
If anyone can give me some advice on how to stop this clunking sound, I would be VERY appreciative. I'm not positive it's the UCAs, but since I've replaced everything else, I think it must be them making the noise.
