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!
