wheel bearings?

I have a 1987 MJ 2wd. Just wondering if changing the wheelbearings is the same way I've been reading about on the dana 30?

Alot simpler. Remove tire, remove caliper, remove dust cap, remove cotter pin, remove outer bearing, remove disc, knock out inner bearing and seal from disc. Get the bearing sets, w/races, and new seals. Remove old races from disc with a punch, brass prefered, but I've done it a hundred times with a steel one. Install in the reverse, oh yeah, don't forget to pack the bearings with grease. Just did the pass side of my 2wd, need to do the drivers side. Easy job. Good luck.
