Hi all. New to the forum but need help. I have a ML270 (2000 model) and it has developed a knock. When accelerating or braking it is fine but when coasting to a stop from 30 it has a loud knock from the rear end. This only happens when coasting, not at any speed on the accelerator and goes away on the brakes. I'm thinking more driveshaft/diff than anything but wondered if anyone had heard of this. It's an old bus now and has 130k on the clock but generally been a good car. Any advice would be helpful!
Cheers
