Hey, just a quick question. I left for work this AM and discovered that the city plow had left a nice pile of snow at the end of the driveway. I should have know better that it would have been hard as it was -20c out but either way...i went over it backwards without a problem.

On my way to work and on the way home though I have since discovered that there is a high pitched squeal coming from the rear passenger tire. The sound is loudest at city speeds but is still there while driving highway speeds, though is not as loud and seems stop while braking.

Any ideas before I take it in to the shop to have it looked at??
