Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.

Do you have 5 lugs or 8?

Dual wheels?

Full floating axles?

8.50 ring gear looks like this

Customer: replied 3 years ago.
5-lugs, not duall wheels in rear, single, I believe semi-floating.
Expert:  Super Mechanic replied 3 years ago.
Ok, let me give you the steps for that. First you will want to take the axle shaft out.


REAR AXLE SHAFT

  1. Raise vehicle and remove wheel and brake drum.

  1. Raise and support vehicle.
  2. Remove wheel and tire assembly.
  3. Remove brake drum.
  4. Remove carrier cover and drain fluid from axle. Remove gasket.
  5. Remove locking screw.
  6. Remove pinion shaft as follows:
    1. On models less locking differential, remove pinion shaft from case.
    2. On models with locking differential, remove pinion shaft partially and rotate case until pinion shaft touches the housing, Fig. 1.
    3. Using a screwdriver, rotate lock until it aligns with thrust block.
  1. Push axle shaft flange toward differential. Do not hammer the shaft to move.
  2. Remove lock (13), Fig. 2, from button end of axle shaft.
  3. Slide axle shaft out from housing. Do not damage seal.
  4. Using axle shaft bearing remover tool No. J-23689 or equivalent, remove oil seal.
  5. Remove bearing as follows:
    1. Using axle shaft bearing remover tool No. J-23689 or equivalent, (for 8 1/2 ring gear), or axle shaft bearing remover tool No. J-29712 or equivalent (for 9 1/2 ring gear), carefully pull bearing from axle.
    2. Insert appropriate tool into axle bore so it grasps behind the bearing. Tighten nut and washer against bearing face, then pull bearing out using slide hammer with adapter tool No. J-2619-01 or equivalent.
  1. Reverse procedure to install.

This is what the puller looks like, in case you don't know. You can normally borrow them from Autozone.

Thank you, XXXXX XXXXX bearings and race pressed into end of axle tube?
Expert:  Super Mechanic replied 3 years ago.
Yes, that is what the puller is for. The seal you can normally just pop out with the axle end or a prybar but the bearing and the outer race are pressed into the housing. The inner race for the bearing IS the axle itself, so you will want to see if there are any burrs or gray spots on the axle, (where the bearing rides) and if so, there are sometimes "axle saver" bearings, with seals built in so you don't have to replace the entire axle, (which may be costly)
