Does anyone know what other ring and pinion would be compatible with the W163? I have an 01 ML500 and would like to change the ring and pinion, (ideally, the entire pumpkin) but can't find any cross references. Earlier ones had 3.46, mine has 3.70.

Similar vintage S/CL class with same motor? The 5.0L and 5 sp auto tranny is used throughout the product range, so I am guessing that MB wouldn't spec something special just for the w163 diff.

Regards,
Jerry
