Truck having bouncing problems on take off from a stop sign

RE: Truck having bouncing problems on take off from a stop sign
I still would like to know if it will really spin the tires on pavement or not? If that 5.2 won't spin the tires there's something more wrong than a loose bearing or suspension. That's what is making me think that something is stripped, broke, or burnt. Those "shin buster" axles; that Rupe mentioned, are splined. Sometimes the splines start to strip off one axle. Under light power the vehicle will pull & on a slippery surface (in the dirt) it will spin the tires. But on the pavement there is to much traction and the axle slips, bouncing the rear end.

Somewhat similar things happen if the clutches in the transmission aren't fully engaged or a driving shell is partially stripped. Just because it was just rebuilt doesn't mean that something isn't wrong with it.

All I'm saying here is that you might want to have someone watch the back tires in a paved parking lot just to see if they will spin. If they won't spin I think you are going to find another problem.

Please keep us posted.

Garner makes a good point on the trany issue but my experience tells me that any problems with axle splines will make one hell of a racket and you have already mentioned there's side play in the pinion so I figure you at least need to take off the cover and inspect those rear end parts. If you are not sure of your original diagnosis then maybe seek a professional opinion for the diagnosis and think about doing the repair yourself based on that opinion. The repair price estimate may sway you one way or another if they give you a full report on their findings.

Now, if it's a posi style rear end all bets are off till there's an internal inspection. They have clutch packs, gov weights, ratchets, etc. I have also seen the spider gears broken and skipping under load. That's an easy fix for the DIY type (nothing to set up) but the parts ain't cheap.

OTOH, you have already said there's axial play in the pinion so an inspection is first and foremost before deciding which way to go with a repair.
