There still is a posibilty its an open diff. since you just spin one at times. it is easy to spin both with an open. the best way is still to lift it up,but not the funnest! all fronts are open so if only wheel spins its normal.

 

ok so shouldnt the tires swap then though from left to right ? thats what happens right ? and what about 4 low? what makes that so different to crwal through differnt areas i cannot do with 4 high ... also .. 4 high in reverse dont seem to be very torqued.. seems gutless ? but in 2wd its fine and 4 low ?
