Are you not adding the shims to the bottom to center the knuckle, but the top shims under the steering arm are to add/subtract knuckle bearing preload ( I.e. if you remove shims it increases preload and if you add it decreases).?
First questions regarding trunion bearing preload.
Do most people re-install the shims that came out of there knuckle or go with the rebuild kit shims?
My trunion bearing preload pull-test was at 3lbs only before disassembly. Do I attribute that low number to worn bearings ( they were worn) or...
