Alright guys got a question for ya. My truck is making this really annoying squeaking noise when I'm in reverse and its only in reverse. The other night I jacked it up put it in nuetral and manually turned the driveshaft to check that but no noise. I also started the truck and put it in reverse while it was in the air again no sqeaking. Put the truck back down backed it back in the garage and its squeaking I have never heard of this but I'd really like to fix it if someone knows whats wrong thanks- zach

Yea if I jack the rear up and put it in reverse no squeaking, let it down and back up then its squeaks and I have no clue what it is.

Old thread but I figured if anyone else ever has the problem I'll post up. I found out it was my u-joints they were completely dry and rusted.

i was just going to say U-joints need to be greased or replaced. glad you found the problem man.
