You can get in trouble with the pinion bearing preload if you pull the yoke off without disassembling the rest of the diff. You should carefully check into that process before you pull the yoke. I am not personally familiar with that truck but some diffs use shims and you should be OK. Some use a crush sleeve and you would be in trouble.
