Thanks to all the information on this Forum, I decided to get the crankshaft balancer replaced on my 2000 ML320 since it was part number 112-035-00-00. The vehicle has 38,331 miles on it and is going out of warranty next month. It was due for its next FSS servicing last week and during that time I wanted Mercedes to go over it and fix all outstanding warranty issues such as the auxilliary fan wiring harness with larger fuse, the window switch module that goes bad and thought I would get the crankshaft balancer replaced under warranty if they would cover it. If they would not fix the crankshaft balancer under warranty, I told them I would pay to have this done so that I would not have to undergo the aggravation of it coming apart at some inconvenient time. If this part ever gets recalled, I would just try to get compensated for the repair I previously had done.

When I went to pick the vehicle up, instead of replacing the crankshaft balancer, they replaced the belt tensioner under warranty(part no. 112-200-09-70). I complained to the service writer and he told me that I did not know what I was talking about and this part was indeed the crankshaft balancer. In my opinion, Mercedes Benz and the dealerships are doing a disservice to their customers. I buy a Benz but receive the service quality of an American brand dealership. If Daimler-Chrysler keeps this up, they will not be around in the future in their current form.
