well there is soem to it, have u taken out the axle yet??? you need a pair of axle wreches to do that, then once all thats off, u take a hammer claw and pry the bearing seals out, but be carful to not touch the houseing, or bend it should i say, then tap the bearings out, then once they're out u should freeze the new bearings and grease them up and tap them in with a socket slightly smaller than the outer race, or anything that will tap it in straight, then grease up the seals and tap them in without damaging them!!!!!then reasemble ur rear end.
