Bad U-Joint?

Well i dont think my truck wants to go to college either...
its making a funny noise in the back of the truck. Sometimes it does it other times it doesnt. And when i first shift it into reverse or drive it shifts loud. Im thinking its the U Joint in the rear driveshaft. It hasnt ever been replaced so i think its that. Sometimes it just does it under acceleration other times when just going down the road. Does this sound right to you guys. Or should i pull the diff cover and check my rear gears to make sure they are ok?

Re: Bad U-Joint?

Sounds like the u-joints to me. My old u-joints made all kinds of noise. Whenever the truck shifted, it made a bell sound through the driveshaft. At higher speeds, there was a constant growling noise. Once I got the old ones out, they just fell apart in a cloud of rust-dust.
You should go ahead and put in new u-joints. There not too expensive, or difficult to swap.

Check them for slop. In other words, chock the tires and put the truck in neutral. Twist the driveshaft and check for slop in the universals.

When the one at the pinion took a dump it made snapping noises under load. It was the rustdust bearings getting ground up.
