My girl friend's 99 ML320 just developed a vibration in the front area, that occurs mostly when the car is first put in reverse, but seems to continue at a lower level in Drive as well, again while just sitting still. This happens when the car is first started, not moving yet. The vibration seems to be emanating from the left front quadrant of the engine compartment, but I can see nothing there out of the ordinary. Checked PS fluid; seems at right level.

Anyone have some ideas??
