this jut poped in my head and i thaught it would be worth trying to explain
what if you take the transfer case front axle and 4wd selector swith and lever out of a 88-98 chevy truck and out it in the newer push button 4wd trucks i bet that would eliminate the taction control and problems the newer ones has
i jsut thaught of this it made me think and im still thinking it would work
