This is a 00 ML320 with 40K miles on it.

I've never had your problem, but it could be the Harmonic Balancer, tensioner or the belt or a combination of these parts. On my 00 ML430 they replaced the tensioner & belt when it was in for replacement of the problem Harmonic Balancer. This was done under warranty before the Balancer failed. If you haven't already read about the Harmonic Balancer problem check out this thread Crankshaft Balancer Failure! UPDATED
