190e differential question
Hi all,
I'm searching to see if this is a common problem. My '86 190e has a whine that sounds like it is coming from the differential. The whine is most pronounced when you are putting pressure on the drive train (i.e. accelerating). The whine begins at about 15-20mph and gets louder as you increase speed. At constant highway speeds the whine is minimal.
I recently jacked the car up so the rear wheels were off the ground and ran the car in gear at varing speeds. The sound was not as pronounced while I did this test , but there was a noise that very well could have been the whine. While the was running and in gear I used a stethoscope to listen for the whine. It was difficult to tell exactly but I'm 95% sure the whine is coming from the differential. Wheel bearings did not sound out of the ordinary and the transmission sounded good. I changed the oil in the differential and it was dark grey to almost black which surprised me because I just changed that oil no more than 6 months ago. There was no visible signs of metal shavings in the oil.
The car only has 117,000 miles on it.
Is this noise comon for these cars? I can't believe Mercedes would produce a car that has this kind of a sound and /or a differential that doesn't last. If it's not common then it may be ok for me to replace the differrential with a used one. New differentials are hard to find and spendy.
Any good suggestions on where to buy good parts including seats?
Thanks for any help.

RE: 190e differential question
Thanks for the replies. Unfortunately the adjustments are most likely not as easy as it sounds. I will have to let you know how it turns out. Thanks for the parts offer duxdevil, I will keep it in mind.
Later dudes!
