I have a 97 520i with 105k miles. I'm experiencing a rumbling, poss bearing noise at 35-50 mph.
It appears to be coming from the rear. A friend warned me it could be the diff, but I think its possibly bearings, as the noise goes away if I turn to the left. I have recently replaced a front bearing after finding I was able to get play on the front wheel with the car jacked up. But all other 3 wheels feel solid as a rock!
Another possibility is handbrake shoe fault. Also very occasionally I get a screetch like a stone was trapped in the disc but then it goes away for a few weeks only to briefly return again
Has anyone experienced anything similar. Also if the noise dissapears turning left, does this mean the problem is on the left?
Suggestions greatly appreciated
