Attention: TDR Forum Junkies 
That's the sound my 3500 made.
I was climbing a 20deg incline dirt road at the county dump a week ago. Radio on, AC on, windows closed doing about 15mph. Suddenly I heard a constant slow but ultra loud metallic screech outside my truck. Figured it must be a dump caterpillar, with a bad bearing. Looked around and I was alone. Opened my window, still driving slowly and found the noise was coming from under my truck. I let off the gas and slowly stopped, and the noise slowed and stopped at the same rate. I put it in reverse, backed up (no noise) for about 20 feet. I braked hard, then proceeded forward again up the hill. Noise was gone. I have driven 200 miles since, and heard no more metallic screeching noises.
Don't know what components I should check for possible wear. Brakes, or driveline support bearings?
Any advice and experiences welcome.
One other thing. Leaving the car wash about 300 miles ago I drove with the parking brake set for 3 miles in the city. I finally stopped after the third driveline vibration event to see if I had a flat. Tires were good, but I could smell hot brake pad. That's when I discovered the carwash guy had set the brake. I never use it, and just didn't notice the light on the dash that day. Too busy thinking about other things I guess. Could this be the cause of my loud screeching?
Replaced the rear pads about 35K back, and the fronts about 20K ago.
Getting ready for a cross country RV trip, and need to have the truck 100% before we leave. Help!
