Let me know if you have any questions about this. Even if you dont have this problem its a good thing to know.
I had the gears in the rear end of my ram 3500 changed and after 500 miles the pinion preload loosened up. I was getting a distinct wine while slowing down but could not determine the cause of the sound. In the 1 ton truck with extended bed and cab the differential is waaay behind you. So i strapped a camera to the underside of the truck and went for a drive. In this video what you are seeing is accelerating up to about 50 MPH then letting off the gas. No braking until the end at all. The noise you hear is all differential.
I took the truck back to my mechanic and sure enough the pinion preload had loosened up. After a quick tighten and re torque the truck was running quiet again.
If your only symptom is a whine while slowing down preload on the pinion is a good place to start. I am not sure what it would sound like on a smaller gearset tho, This truck has an 11.5 inch ring and pinion set so the gears are a bit noisy to begin with.
This is my ram 3500 dully diesel I had it fixed at Mid Michigan Transmission and the guys there are great!
