Back to the floating king pin discussion.
I can see why they originally floated and that's fine, a good system when fixing worn parts is as simple as just pulling new spindles off the shelf.
Fast forward to today, those parts shelves are pretty empty of new spindles.
I am very much an advocate for the loctite bearing retaining compound as used to fix the bushings in the spindles. Doing this with the spindle in place to line them up will result in a tighter fit overall then even a new truck had.
When things wear it will only be the bushing and pin, and can be replaced without machine work or a new spindle.
Also compare the 1/2 ton spindles, king pin, and relative bushing size to that of a 3/4 or 1 ton. They are all similar in size, the 1/2 ton does not have undersized bushings for the application or anything unusual about them beyond full floating. Therefore I'll argue that if the larger trucks do well with fixed bushings then so can the 1/2 tons these days.
The corvette article linked about the floating bushings is about NOT using a center punch to rough up the spindle bore to hold the bushing in place, which I agree is bad practice. The bushing may not have turned but there will still be just as much slop after the two pieces worked together, still nothing filling the gap.
There is no mention of using loctite to firmly fix the bushings in the bore, the article is not quite applicable to the discussion at hand.
