Everybody kept telling me it was tires, which didn't seem right to me, so I put it on jack stands, removed the rear differential gears, and ran the truck up to 65 mph in gear. The noise is identical to when it's running down the road at that speed. So. That rules out tires, wheels, hubs, rear differential, etc. I could not see anything visibly vibrating under the truck when it was making the noise/vibration.
Nothing leaks, the drive shaft weights appear to all be there, and I can see any other indication as to where to look for the problem. Any thoughts what I should try next?
have the same problem?
