clunk noise....help.....

[huntingjohn2777]

clunk noise from rear end when accelerating from a stop. Also tried it with brake held and shifting from reverse to drive multiple times. Every time makes loud popping or clunking noise from front of rear end. U-joints look good and pass shake test..........Please help......pulled truck from ditch last winter....also last time I put rear diff fluid in I think i put 80-90. not limited slip like it should of had.

Clunk just when accelerating? Sounds like you got gear probs in the diff

Oh yeah...you got Stanley for your location. Which Stanley if you don't mind my asking.

I have the exact same thing...its probably your splined slip joint on the yoke of the drive shaft and probably the carrier bearing. 1050 installed from the dealer! or 60 bucks to have him take it apart lube it slap it back on and drive it for a while.....This is a somewhat common problem I am finding out. Mine has been doing it for years....finally popped for a new drive shaft to get it done right.

This sounds similar to what my 04's been doing for years, but only after shifting out of reverse (backing out of a parking space). Dealer could never figure it out. It's been doing it pretty much since I got the truck.

Mine is doing the same thing. I looked at it the other day when I had it on the hoist and I'm thinking it's coming from my slip yoke in the drive shaft. I need to have someone drive it and watch and see what is moving because I feel the clunk too.
