Please help!!! ('89 BMW 535i)

When driving between 20-40mph, a rather loud vibrating is felt coming from the front/rear driveshaft. I've been told that the "Center Support Bearing" and "U-Joints" need to be replaced. Is this common with these 535's? To me it seems that there's also a slight vibration on the front right-wheel. Vibration goes away after driving 45mph, a few days ago the vibration can still be felt when driving up to 65mph. Does anyone have any suggestions? ...and where I can find these parts cheaper than at the dealer? Any help, suggestions or recommendations are sincerely appreciated.

the center support for the drive shaft is mounted in rubber and it gets swaybacked with age and then it causes an out of line condition in the shaft until the RPM is higher.

Bad news is it usually requires the exhaust be lowered to get the shaft out to replace the center carrier.

This is a sample of the exhaust issues.

Get a shop to do it unless you have a torch in the garage.
