Noise developed a few weeks ago. Thought it might be the brakes. Replaced front rotors and pads. Replaced rear shoes and turned drums. Same old squeak still exists. Seems to be coming from center to rear center of the vehicle. Does not squeak if I just roll backwards in neutral. Only squeaks in reverse. Speeds up as speed increases. Does not matter if on brakes or not. Does this on incline,decline, and flat road.

sounds like a bad universaql joint. unbolt the drive shaft in the rear and move the u joints, if they are stiff then replace them.
