Sooooo, your tires are spinning extremely fast.....which means that your truck is now very fast.....the tires turned into pizza cutters due to centrifugal force.....
But the question is, did they explode or de-bond from the wheel?
It will appear, if your truck is on the stand, that when you give it some trigger that the tires cannot handle it.
Did you put it on the ground and try it? If you haven't changed any gearing, only the axle shafts, there should be no big difference other than maybe a very minimal increase in immediate power to the wheels themselves.
It IS a good idea to reset your slipper for the new axles as the settings WILL change with those new cvds.
