I'm currently looking for a mechanic to check the car out, but I want to hopefully get an idea of what could be wrong before I bring it in. The car has about 56K miles on it and I haven't had any real problems with it up until now. Recently, I noticed that it's been making a strange high-pitched noise when backing up. It's not the normal "rmmmmm" noise that I usually hear when backing a car up, but more like a squeal. The car goes into reverse without a problem, except for making this noise. Any ideas from the car people on ATOT?
