Seen this happen a few times over the years. When doing the one-wheel-peel, you're forcing the differential to differentiate at a very high speed/high load. As fast as your wheel is turning, the differential is turning twice as fast. It ends up inertial welding the pinion mate gear to the cross shaft. Only luck I've ever had getting it apart has been to sacrifice the differential (e.g. red wrench! .....acetalyne torch). Think of it this way though.....you get that brand new Auburn Pro and the wife can't really argue about it.
