Remove the differential cover let fluid drain. While draining remove the tire on the side with the bad bearing. Remove the brake drum. remove the spider gears if it has a open diff. If not an open diff you will need to get a book at a parts house about $20. After removing spider gears remove the axle C-clip then pull the axle out. You will need a bearing seperator to remove the bearing. An oldschool trick for installing the new bearing with out a press is to stick the axle in a freezer for about 2 hours about 30 minutes before removing the axle put the bearing in an oven at 350 degrees (wear gloves when getting the bearing out) Quickly remove the axle and then remove the bearing and immediatly install the bearing it should drop onto the axle right where the old bearing was I like to take a puch and tat the inside of the bearing to make sure it has seated all the way.
Any questions please let me know
Have a great day

They should be replaceable w/o pulling the axle. Imagine a common nail; you have the shank of the nail with its point and the flat head on the other end. Your lug stud looks a little like that except the part that comes through the axle flange. It is a little larger than the threaded part and has "lateral lines" machined into it to grip inside the flange. Otherwise it would spin either way when you tried to tighten or remove it. To get the broken ones out, use a high quality flat end punch and a hammer to drive them backwards (toward the center of your differential) and eventually out of the flange. Look for the area that will give you the most room so they will not hit aything while they are backe out of the flange. The new studs can be installed in the reverse manner. When you get them just barely started through the flange, use your fingers to twist them back and forth to "feel" for the grooves where the old stud was seated. Once you get it barely started in the grooves, grease the threads, slip an old 1/2 inch drive socket over the new stud (make sure it doesn't fit tight) slip on a thick flat washer or 2--3 thin ones, turn your lug nut around backwards so the tapered end faces out and begin to tighten it. Go slow, make sure the new stud pulls through the flange evenly. Take the nut, washers and socket off every now and then and look at your progress. When the back side of the stud is seated on the back of the flange, you're finished. Now, always grease the studs. ALL OF THEM, EVERY WHEEL. The monkeys that put on tires these days use impact wrenches and if you just have to let them do it, grease will help you loosen the nut if you have to and it will help prevent future failures. A DRY stud and nut causes a twisting motion to take place in the body of the stud when its tightened. This leads to premature metal fatigue.

You will have to remove the differential cover on the rear end, in the center of the gear cluster you'll have to rotate your axle until it exposes the ends of the axle shafts, push in the axles as far as you can from the brake pad assembly area, then, there this a C clips that slips into a groove on the end of the axle, you'll have to reove the C clip to pull out the axle.
