Reading elsewhere (
http://forum.ih8mud.com/1032753-post.html I see that Poser says that the shims work as follows:
Top: used to adjust pre-load
Bottom: used to adjust alignment of the knuckle with the axle centerline.
This conflicts with the Haynes manual which says "If necessary, bearing preload can be adjusted by ading orsubtracking the same amont of shims from both the upper and lower knuckle bearings."
And thinking about it more it is not clear to me whether I should be ADDING or REMOVING shims. Instinctively it seems like adding shims would REDUCE pre-load because the bearing cap would not be inserted as far into the bearing.
I'm gong to start on my left knuckle now...hopefully someone can provide me with some definitive answers before I get too far...
