Mercedes-Benz ML320 Problem Report
Mercedes-Benz ML320 Shutter or Rumbling When Truning at Slow Speeds
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.
