Louder than normal rear end noise. At first thought it was tires. Mercedes dealer quoted me $ 3,200 plus tax to replace rear differential. Is this a common problem for Mercedes at this mileage point? My old Buick went 160k miles w no problems.
Rear Differential failing. Very loud gridding noise from rear of the car while driving.
Just had a mechanic talk about the possible high cost to repair, two weeks in the shop...recommend to get a used differential. He said it is uncommon for this to happen and that most issues are at the 300000 mile point. I really enjoy this car but the last thing I would expect is this type of problem.
$4000 to $5000 to repair. Looking at new cars now not worth that level of expense.
I just have to spent $2300.00 to fix the differential noise. At such low mileage this problem should not arise. Mercedes Benz subside the retail cost of the part by 50% and I have to pay to dealer full labor charges and 50% cost of the parts. Mercedes Benz should fix this at no cost to consumer as this is mfg. defect.
Experiencing grinding noise from rear end. MB Dealership said it was the rear differential. They said it was strange at such low mileage. Waiting to hear if MB will assist with the cost/repair. Very frustrated!!!
Repaired today. Bill was $600 for seals and a couple of service things
