2007 Mercury Mountaineer Premier

I have a '07 Moutaineer that is having the same high pitch squeal at low speeds. I haven't determined if it's front or rear. Is most everyone experiencing this in the rear of the vehicle vs the front? I've also had some popping noices from front right passenger wheel when turning and didn't know if the two were related.

It could be one of the two following issues:

Special Service Message 19946: 2002-2007 EXPLORER/EXPLORER SPORT TRAC/SPORT TRAC/MOUNTAINEER WITH 5R55 TRANSMISSION - TORQUE CONVERTER SHAKE/RATTLE

Some of the above vehicles with 5R55 transmission may exhibit torque converter shake and/or rattle. Proper alignment is required for converter and adapter plate. Misalignment of the torque converter to adapter plate will cause an imbalance. Align paint mark on adapter plate to orange paint dot on converter. Rotate paint dots to 12 o'clock position in preparation for decking to engine. The fly wheel position is not critical. Utilize all new nuts to mount the converter to the adapter plate and to attach the flywheel to adapter plate. Effective date: 9/7/2007

Good info. My '09 has done it from day one. I bought the truck with 60 miles on it. Definitely taking it in to the dealership to have it checked out.
