A further note on the 1 ton knuckles. The ball joint tapers are all correct
because we are using 1 ton ball joints. Where there has been an occasional
fitment issue has been on the tie rod joints. SOME, BUT NOT ALL, of the
knuckles are thicker in the area where the joint is located, and the GMC
tie rod end threaded portion is quite short. Manny has a workaround for
this. He uses a tapered reamer that is the same as the joint, and just
reams the bore a bit deeper. This allows the joint to seat further up,
giving more access to the threaded portion of the joint. It is a critical
reaming operation, and the stock joints vary a bit. So, the castellated nut
and the drilled cotter pin hole sometimes does not index. In those cases,
I fit a distressed nut. They are still torqued to the same value as the
castellated nut, and because I am a belt and suspenders kind of guy, I use
blue threadlocker as well.
