Hello All. I have a 1990 325i Convertible. I have been tracking a noise (bang bang bang bang) and vibration upon acceleration. It almost feels like driving over rumble strips on the side of the road.
So far I have changed the following.
Guibo
CSB (x2)
Subframe bushings (lemf)
Trailing arm bushings (lemf)
Driveline rebuilt at local shop (twice)
Engine mount (passenger side)
Transmission mount
Rear Wheel bearings
Half Shafts (GKN)
The noise defiantly seems to feel as though it is coming from the rear of the car. I do see some radial play in the passenger side output flange of Diff (car has LSD). I did not however see any metal/glitter in the recently changed diff fluid.
Differential issue??? Driveline still bad after a shop looked at it twice???again, I can only feel the vibration when accelerating fairly quickly. Seems to happen before the transmission shifts gears (automatic). Help please! This has been very frustrating. Thanks in advance!
