Brakes, emergency brakes, and U-joints are all good... the noise is still there. It's not really a squealing, I guess, but more of an oscillating squeak-squeak-squeak that speeds up an dslow down with my back-up speed. From insid ethe cab with the windows down, it seems to be coming from the center.
I guess My next step would be to try to locate it while someone else is backing it up... but I'll be tempted to be under it at the time.
