Driveshaft

[VehiX]

The thud happens to me and I also have the whine at lower speeds. I contibute this to fluids. I'm going to lube the driveshaft and change out the diff and axle fluids. We'll see what happens after this.

As long as we're on noises, I have a few that I want to see if are "normal"
1) 60 - 70 mph with foot ON gas - whine from the rear end (I've heard of this problem before when letting off the gas, but not when giving it gas)
2) U-joint type thud or clunk after decelerating then giving it gas again - almost like tranny slips for a second (although I don't feel a "slip") and then engages - causing the U-joint clunk.
3) Driveline noise that sounds like tire noise at slow to moderate speeds. Thought it was tire noise (that's what it sounds like), but it goes away when I lwet off the gas.
4) Sitting at a stop, foot on brake - release the brake and hear a noise like pads were stuck to the rotors or something - it happens before I give it gas, so it's not driveline related.
