tire pressure, shocks or sway bar, steering components. check these.
The torsion keys being cranked differently should not effect the handling as long as the truck is sitting level side to side.
My tire size on the front may be to blame.
Driver Size Tire: 295/ Passenger: 305/ Both 24" Rims
i think that will make a big difference. specially it really need a big time alignment.. the Toe need to be set properly..
THe car is at the paint Shop for Body work and paint.. ones its out i will switch the passenger tire with same size as the driver side and get a wheel alignment.
i let you know what happen..
i did check all you mention and there all good.
