In June of 2003 I had a rear differential replaced. At that time I had 83,000 miles on the car. Since then the rear tires are worn excessivly after only 2000 miles. I went to my local Mercedes dealer and the dealer thinks it's the alignment .I dont think this is true because prior to the differential being replaced I never had a problem with the alignment of the car what so ever. Could an improperly installed differential cause that problem of the wearing of the tires?Also the car had the tires replaced at 63,600 miles and the tires were good until 81,000 miles and within 2000 miles the rear tires are completely bald. I have a 98' ML320. Please help if you have any tips or suggestions.



THank you

Assuming the new tires are any good, it sounds like whoever replaced the differential didn't align the rear wheels properly after they did the job. Replacing the diff will alter the alignment.

Out of curiosity, why did the diff need replacement? Is this a common problem? Is mine next?

have to undergo a 4-wheel alignment. I'm surprised that this wasn't done as part of the service (or at least they should have made you aware of this, since it's usually a separate charge) - perhaps becasue it's usually a separate charge. have the truck aligned and you should be just fine.
