gtdrei, what are torrington bearings?
I believe the correct term is a Thrust Bearing. Torrington is the Manufacturer, now owned by Timken. My tech introduced me to them as part of a strut upgrade. There's a bearing and two washers, and the assembly is installed at the strut top. I was out of town and did not get to see the actual install. Not something you'd do by itself

Well, we've got clanking, twanging, moaning, groaning, sproing, and clunking...
Are yours ajustable end links and what setting are you running?
I finally solved my other clunking (different than loose swaybar mounting bolts now loctited and rod ends clacking below). Caveat: mine is a 986S with GT3 bar and adjustable end links run at full stiff.
Noticeable more at low speed, somewhat intermittent, mine made a clunking sound over small bumps and cobblestone type surfaces. The problem seemed to be that the endlinks would rotate about their axis just enough to clunk up against the wheel carrier. The clunk seemed to rotate the endlink out of the way but depending on the angle of the wheel (or phase of the moon), possibly because it was loaded, it would rotate right back and clunk. This is a different sound than the clacking of bearings in the rod ends or other sounds.
My solution was to fabricate a spacer to change the geometry slightly, and now that one clunk is gone. If you're running in the middle position, then this is not the problem. If you are running stiffer, then check to see if you have the slightest signs of scratches or wear near where the endlinks mount to the wheel carriers.
Good luck!

Please give a listen
Attached (zipped) is an MP3 file in which you can hear what I call the "groaning" of my front (seems to be right only) suspension upon compression over substantial bumps (speed bumps and the like of about 3-4" in height).
What do you think is causing it, and where should I look to fix?
The dealer has not heard it before, last I checked.

Hi Chris, I have that sound too, also from the right front. I just call it the suspension fairy saying 'hi', and keep on driving. It has no negative effect, as far as I can tell, even on the track.

Yeah, I get that too, combined with a metalic clank... no idea where that is coming from... what's more, sometimes I even get a brief clank when I getting out of the car....

Service Bulletin?
Met my service manager at an event this weekend and he mentioned a recent GT2/GT3 service bulletin that might address the noise that you can play HERE. . Apparently there is some lubication goo that can be added to a strut (?) connection.
Anyone hear of this bulletin?

Took it to Stead Porsche last Thursday, the service guy said the only way to solve it is to insulate the springs.

Rockit - is that because Larry's straight pipes are so loud you can't hear anything else?
