So lately I hear this high-pitched squealing when I go in reverse. It's completely quiet when I am in drive.
My first thought was the U-Joints, but both driveshafts have absolutely no play in them and all 4 joints look/feel good. I would hate to go through the effort to replace them and that not be the issue.
New brakes have less than 10k miles on them, and there is no debris anywhere that I can see in the dust shields, etc.
