I have a squeek coming from under the truck while driving. Very noticable when driving slow. I looked at everything under there and have come to the conclusion that the u-joints are making this noice. Can anyone comment? Should I proceed to replace them?

Thanks

 

That was one of the first signs mine were bad.

 

That's all I needed to hear. It's off to the parts store. It only Squeeks in drive, no squeek when in reverse. Is that normal when they go like that, squeeking? I can't see what else it could be. Guess I'll replace them and see...

Thanks for the reply.

 

That is one of the signs. Another is vibration.
