Well the spindle doesnt put any more stress on anything then the stock one and the keys were not cranked at all and truck set completely level and the only "help" they needed were just being cheap parts and the tire size people run quite often with stock steering components as well as mine did before this happned... the stock ones never broke they were just worn so I thought I was being smart by replacing them with new ones seeing the stock ones had 350k plus and were not making noise or anything it was just well past the time of having them changed so dont be afraid of the spindle it works great just get the HD joints and keep rockin
