156k miles; bought it new.

Symptoms include a clunk when making a slow speed tight left turn. I recently replaced both halfshafts, both tierods and all of the front suspension bits, including ball joints, control arms and tension struts and swaybar links. All were torqued to spec under load, and double checked by my dealer when I had it aligned.

I thought maybe the belly pan bolts were loose; I reused them (yeah, I know) and loc-tited them. They were torqued too; and don't seem to be loose, but I suppose that might be the problem. I crawled under it Sunday and re-torqued them about another 45deg; still have clunk.

Strut upper bearings going bad or the strut shaft nut loose?

I'll check the struts, good idea. Thanks.

Good call I would recommend this to. I just finished rebuilding my front suspension which included new sachs struts with the H&R lowering springs. When I removed the upper bearing/strut mount and inspected it, I was surprised to see the amount of deterioration that occurred with the rubber in the mount. While I did not have any noise it was just a matter of time before it would show itself.

Both rear air bags deflated never to inflate again. That was one heck of a bumpy ride to the indie shop. Doing a conversion and getting rid of air suspension. Also DSC 4x4, Brake, and ABS lights came on prior to the suspension. Indie said no go on the gear replacement. I believe he called it the Servo motor needed to be replaced? Whatever it is thats getting fixed. Passenger side valve cover is leaking. Besides the alternator this is only the second big fix in the 3 years I've had her. I feel blessed. She is one heck of a machine.

3 problems this week. Got "Check brake lights & check rear lights" along with washer fluid low (leak is likely as it was full recently).
