    When I come to a stop sometimes I can feel the truck want to lurch foward, feels like Im getting hit in the rear a bit.

    Feels like a shudder of somekind more than a bang that would lead me to believe that its the slip yoke. Thought maybe it could be the convertor but keep it in second so it doesnt lock and it still does it. Trans shifts fine etc so Im thinking it has to be the slip yoke since its such a common problem. Im going to pull the shaft and drive in 4x4 to see..

    Any other ideas?

    sounds a lot like a slip yoke. Pull the drive shaft, grease the splines and the inside of the yoke and reinstall it. See what happens.

    My 94 does that, I always thought it came from the drums, but now that you mention it, a slip yoke makes sense. At some point GM released a special nickel plated yoke, but it's way too expensive IIRC.

    Check the ubolt tightness and the spring bushings also. If you have drum brakes and the adjusters are not equal, it can put the rearend in a bind because one wheel is stopping harder than the other. That tweaks the springs a little and the rear axle can get in a bind.

    Yep plan on checking center pins and ubolts as well as the rear brakes just to be safe...

    I just cleaned the dust out of my rear drums and the noise went away. But mine is only 2wd. So...:dunno:

    Yep I think mine was a sticky adjuster or something, after a few good high speed backups and brake applications it has stopped. I pulled the drums and everything looked okay in there. I greased the slip yoke anyways and found that one of the 4 bolts for the yoke straps was not even finger tight..

    Hasnt done it in over a week..
