Due to slipping clutches in the transfer case, a shudder or rumbling from the center of the vehicle may occur, especially when turning at slow speeds. If the clutches are not too badly worn, changing the fluid will fix this problem. Otherwise, the transfer case will need to be disassembled to change the clutches.Google+

Mercedes-Benz ML320 Problem
Visitor, 2001 Mercedes-Benz ML320, 99,186 mi
When I am coasting very slow such as departing from the curb or slowing for a dip, the car shutters and loses power. If I turn it off and re-start it seems to be fine. It just started yesterday, but does not seem to happen at higher speeds.
