Just an up date. I finally got a chance to go down the road with the 3 degree caster shims I installed in my front leaf spring pack. No more white knuckling it down the road.
I replaced the front shackles, leaf springs, U bolts and added the 3 degree caster shims. My king pins were replaced 3 years ago. Now I am enjoying driving the truck.
