Pulsing vibration

[lolcopter]

Rear end has been rebuilt and had new limited slip diff installed. I just replaced the axle shafts because that was the only thing reused in differential.

Point well taken. Borrow one. If you were closer I would let you try mine for an afternoon drive. We have a machine shop in town that will build you a nice shaft for around 350 bucks ready to slap in and go. Every truck that I have cut down gets the 3/5 static drop, new shaft and I go thru the brakes. Lucky so far, no vibrations. Also, no pinion angle shims. This leads me to believe that your problem may not be in the shaft. I would re-visit my rear end unit for premature bearing wear. Does this vibration have any whining or sound that accompanies it? One more thing, I would have a passenger ride in the bed, laying prone to see if this vibration transfers to the bed and if it is worse towards the rear or front. It will be simple when you do find it.
