How to replace Rear wheel bearings 1995 blazer?

Answer 1

before starting, have a **LOT** of towels handy..you will get messy, and alsos clean all parts very well, that you remove. jack up blazer,remove the rear wheels, as well as the brake drums. remove the rear differential cover. look at the differential, you will see a small bolt in the center portion, remove this bolt, this will allow a pin to come out (they usually fal out after you remove the bolt). after that, have a helper, push in on a axle toward the center of the blazer, when they do, you will be able to remove a little C clip, then just pull the axle shaft out when you pull the shaft, the spider gear will most likely fall out, dont damage it, place it out of the way as well with the washer that came from behind it. do this for both sides, dont mix up the spider gears. lay the axle shafts out ot the way. take a screwdriver, and pry out gently the axle seal on each side, that the axle's go through. you should then be able to see the bearing in the axle tube, you will need to have a bearing puller, basically it goes in grabs the bearing, and allows you to pull it out (rent/buy from local auto parts store). place the new bearing where the old one was, and use a installer tool, to tap it into place. take new axle shaft seals, and tap them gently with a small hammer/socket, (it does not take much effort, be sure not to damage them) after they are installed, put the axle shafts back in, and replace the c clips. after both shafts are back in, and the c clips are re-installed, pull the axles out a little, to seat the clips, carefully check the clips to be sure they are seated in the little indentation on the spider gears. put the pin back in, and the bolt back in, tighten the bolt so it's pretty tight (locktight is a good idea also). put a new gasket on the diff. cover, put the bolts back in, tiighten them in a cross pattern, do **NOT** over tighten these bolts, to much will destroy the gasket and cause a leak. refill the diff. with gear lube. put back on the drums/tires, and clean up the mess..(you will be filthy by now) :) all done.. when you go to put the spider gears back in, it may seem a little challenging, the "trick" is to rotate the whole ring gear assembly,and let the spider gears "rotate" themselves into place, (before installing the axle shafts. you may get lucky and not have the spider gears come out, if your careful. it may seam like it's complicated, but it's actually quite simple..two hours approx or less to do from start to finish. clean everything you can with paper towels/clean rags. paint the cover while i'ts off to make it "pretty". after you have done one, youll be amazed just how easy it is, and the really scary part, that one little bolt, is the key that holds the whole thing together..
