Ok gruppe - I thought that a fresh post would be the way to get a few commnets on this continuing problem. I have a slight vibration and occasional roar coming from the rear of the car. I read a few of the old posts that are leading me to the subframe bushings, but I have a question for everyone. I have noticed recently that the car seems to 'scoot' around slow turns, such as in a parking lot. It makes a horrid noise and seams to slide vs. track as it turns. Is this a symptom of the subframe bushings? Just to list everything that I've replaced (mostly out of frustrations):

Driveshaft
Guibo
Center bearing
Pitman Arms
trans mounts
motor mounts.

Now, I am missing a hubcentric ring on one of my wheels, so I would expect a little vibration, but it comes and goes at different speeds which I find odd. Anyway - feedback would be greatly appreciated!! Thanks!

It's not unusual for vibrations to come in at specific speeds (usually 50-60mph and 100-110mph in my case) which makes it easier to spot a hub, brakes, wheel, problem.

It's once these have been exhausted or the vibration is constant that other things come into play. Also you tend to notice vibrations from the front more than the rear. I have a buckled wheel which I only use on track, and braking from 130-80mph, or 70-50mph I get a terrible vibration through the pedal and steering wheel. After putting the buckled wheel on the back I don't (seem to) have the vibration - I know it's still buckled but I can't feel it.

I'm good with a little vibration, especially at 200k miles, but the sound is what gets me. I think that bushings are in order, but would like the gruppe's ideas. If it means anything, it seams to have gotten worse when I upgraded to the M5 Touring rear sway bar.

Thanks, :confused:
