Question Grinding noise 94 325i

I've got a 94 325i, automatic, with 102k on the clock. Recently I started hearing a grinding type noise and feel vibration from under the car when turning at low speeds or from a stop. More specifically it sounds like I'm driving over a rumble strip on the highway. The sound appears to be coming from around the transmission area. I checked fluid levels in the trans. and all seems well, no burnt smell or dark color.

The car runs and drives fine otherwise. Any ideas?

Thanks,

Steve

Check the drive shaft ie, the guibo or center support, the guibo is that big rubber thing that connects the shaft to the trans....

I second javier, check the center support. Sounds like it's on the way out.

Power steering leak? Our cars are known to leak power steering fluid.

I read that it shouldnt be too hard to replace the clamps on the hoses. That is whats causing the leaking. Mine leaks really really slow, so i havent addressed it yet.

Hello all,

I found the source of my problem. The exhaust mount at the cat had been bent just enough to cause contact with the body when turning. I now recall having driven over one of those 'speed mountains' they put in these days in parking lots, and hearing a scraping noise; I bet it happened then.

My driveshaft and 'donut' appear to be fine. Thanks for all the suggestions!

Steve
