This post is about the shims that are on the top and bottom of the kunckles. A buddy of mine was helping me tear down an axle and before I knew it, he removed the knuckle bearing preload shims without marking. About all I know is that one pair goes to the left axle and the other pair to the right axle. I looked at coolerman's faq https://forum.ih8mud.com/40-55-seri...-knuckle-centering-tool-instructions-faq.html and he used an SST. Without one, is there a way to tell on the origional shims which one goes where? IS one usually thincker than another?
