There are three distinct noises coming from the drive shaft and/or differential area of my 1990 190E:

1.) A scraping sound when I first begin to depress or release the accelerator.

2.) When I let the car coast to a stop, starting at about 25 mph there is a whining or droaning sound that winds down with the speed of the car.

3.) From a standstill if I accelerate firmly to, say, 10 mph and then let off of the gas, there is a pause and then a loud clunking sound.

The only thing a dealer and a mechanic have found wrong is the front flex disc is worn. Could that be all or just part of the problem?

Thanks in advance!

That could be most of the clunk. The whine however is in the diff. I seen many faulty ones.

Okay, the scraping and clunk (what a combo!) are probably the flex disc, but the whine is the differential? Does the differential need to be replaced any time soon, or can I change the fluid and igore it? Any info is appreciated. Thanks!
