Stop in for a cup of coffee

The best way is without the carrier in so ALL you feel is the yoke and pinion gear resistance. But you can do it with it assembled but you just have to be careful. The way I do it, if I HAVE to do it assembled is, tighten it down a little too much first, so I get a feel for that, then back off and ease down on it from there. With blue Locktite in it of course.
If it is a solid shim pinion, then the yoke nut just holds everything tight, yes? I think the problem he is having is the pinion depth is wrong, which is the shims. The nut is just holding everything tight and holding the yoke on. The crush sleeve needs to have it snuck up on.
