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.
having what I would identify as the exact same sound. Loud high pitch squealing that sounds as if the emergency brakes are left on. Gonna take a look tomorrow and try an grease the rubber boot to see if it's gone.
