Hi folks. I have a 90 735I. couple weeks ago, i noticed, when cruising down the highway, that when i pressed on the accelerator, the car would have a noticable push to the right,(a push from the rear, not a front alignment issue) and when letting off the accelerator, it would come back to center. this past week, i started to hear slight clunking noises when making left turns, and more of a squeeking noise when making right turns, all noises from the rear. I also noticed when going down the highway, a momentary jerk of the car, like i had just tapped the brakes.
any guesses? rear wheel bearings? or is this a gear/rear diff. problem?
Thanks

Well, there's the wheel bearings like you said but also there are universal joints that connect the two rear axles to the differential. At 15 years old they may be worn out.
Probably nothing to do with your current problems, but here's a couple of other things that often need attention with these cars at the age of your car.
-Driveshaft. The universal joints wear out and you get some vibration in the drivetrain.
-Thrust Arm or Control Arm bushings in the front suspension. They're not expensive but they are a TOTAL pain in the butt to change. If you're still riding on the old ones you should plan to change these because worn ones will eat your tires up.
Gale's page at http://www.nmia.com/~dgnrg/page_2.htm has some info about both of these issues.

Thank you for your input! I did have the entire front suspension changed out in July 2004, so appears we need to look from the driveshaft on back! thanks again
