grinding from the rear end

135

Asked by Oct 04, 2013 at 09:33 PM about the 1990 BMW 3 Series 325is

Question type: Maintenance & Repair

Over the past few weeks I have noticed that there is a low, grinding, growling sound
coming somewhere in the rear of the car. Some things I know:

A) it's not the breaks
B) only happens when the car is in gear
C) only happens when the clutch is disengaged (not depressed)
D) is mainly noticeable while decelerating, but not hard deceleration
E) is very faint or unnoticeable while accelerating
F) seems to get ever so slightly worse every time I drive it

I'm about to order a 17mm hex driver and change the fluid in the transaxle, but my
mechanic says he thinks it's a CV if anything. Any additional thoughts?

Growling grinding is usually a bearing or CV joint. So your mechanic might be right. Did you check the center support bearing on the driveshaft?

Pretty sure I replaced that when I first got the car, but I'll double check that. Thanks for reminding me. Well I guess a CV would be better than the diff.

I agree with Tom....it is likely differential or flex disk related.....especially if you notice a slight chugging when going up hills.
