This past week, on three occasions I parked facing down a rather steep hill, and when I did a U-turn from my parking place, my car made a very loud high pitch squeaking noise.

When I park on a flat street and do a U-turn, my car does not make the noise. Any idea as to the cause of that noise? Is it something I need get repaired or looked at right away?

Thanks.

P.S. The car is a 2005 special value package (DX auto w/air and power windows) and has under 40k on it.

Does it do this EVERY TIME? Station someone outside where they can listen while you do this. If they can pinpoint the location of the sound, that will help.

My suspicion is that the steep downhill causes the front suspension to compress a little different. That in turn causes different toe in the front wheels, and you hear the tires squealing against the pavement.
