Strange noise from the rear
My friend just got a 2002 ML320 with 50,000 miles. He just noticed a strange noise coming from the rear while driving. You can really hear it when driving at about 45 mph. woooooooooooom. Especially on the highway and when pressing on the accelerator. Any help would be appreciated. He got a car from a Mercedes dealership, and the car was suppose to be certified pre-owned.

RE: Strange noise from the rear
He took the car back to the dealership, and they kept it for a day. When he picked up the car, they told him that they've changed the fluid for differential and the noise was gone. WRONG, the noise is still there and it's definitely not a tire noise. The noise is heard when going around 45 mph, take the foot off the accelerator, it goes away, press the accelerator again and it comes back. Any thoughts?

does it comes on with the differential lock "on"?
ask your friend to try with and without lock.
compare and see if it doesn't go away.
too difficult without hearing it actually.
in noises, the mechanic doesn't have to be an MB experienced to detect them.
