Sometime back, I removed the rear anti-sway bar and associated fittings and drove the car around town. The clunk remained.

WOW! I haven't been back in this thread for a while.
Unfortunately, I don't really have any progress to report. Since my last post I have replaced the axles, thinking maybe one or more of the CV's were bad. This seemed to resolve the clunking initially, but it returned in almost no time. I've also replaced the engine and transmission mounts, suspecting one or more of them to be the culprit...no joy. Clunking still happens. Seeing Warrens post, I'm reminded that someone once posted hearing a similar clunk. They ended up installing some heavy duty foam padding around their sway bar, where it passes across the transmission crosmember. This apparently did the trickk for them...the sway bar was bumping the crossmember. I think I may give fmarin's idea a try and remove the sway bar to see if this does it for me. It's worth a try. Randy

Hey. I think my problem is solved. Bad wheel bearing. Nothing more, nothing less. $45 for the bearing. Another $25 to fabricate a puller. The bearing came out quite easily as it was a cold day (so the bearing was cold) and I heated the outside of the axle control arm with a propane torch. Hot to the touch, but not burning hot.
Interesting that the bearing made no noise when the wheel was rotated; even listening with a stethoscope. Here's something I found out. All the Porsche manuals give a torque spec of 34 ft-lb for the bearing cap bolts. Turns out that this spec applies to the 10 mm bolts used on most models. The bolts on my 73T are 8 mm. My mechanic friends say an 8 mm will strip or twist off at this torque. The correct torque for a standard 8 mm bolt should be about 18 ft-lb. |

well it sounds like it's going to be a wheel bearing party this weekend... i've been chasing the same problem on my car for years. i was convinced it was the top of the shock mounts moving. same issue, as the noise would arise after a right to left turn transition. time to get on it.
thank you matt
