CAUTION: Do not loosen the rear axle wheel hub retainer until after the wheel and tire assembly are removed from the vehicle. Wheel bearing damage will occur if the wheel bearing is unloaded with the weight of the vehicle applied.
With the vehicle in NEUTRAL, raise and support the vehicle. For additional information, refer to Section 100-02 .
CAUTION: To prevent damage to the brake hose, do not allow the disc brake caliper to hang suspended from the hose.
Remove the brake disc.

Using a rubber hose approximately 37.5 mm (1.5 in) long, cover the stabilizer link bolt threads and nut.
WARNING: The bolt that retains the upper ball joint to the knuckle is longer and it has fewer threads than the bolt that retains the toe link to the knuckle. Switching these bolts during installation will prevent the pinch arms on the knuckle from correctly retaining the toe link to the kBad right rear axle.

CAUTION: Do not use a hammer to separate the outboard CV joint from the hub. Damage to the threads and internal CV joint components may result.
CAUTION: Once the outboard CV joint separates from the hub the knuckle will continue to pivot until the brake backing plate presses against the suspension lower arm. To prevent damage to the brake backing plate, immediately after separating the outboard CV joint from the hub, rest the knuckle on a cushioned support that is tall enough to keep the backing plate from pBad right rear axle.

Install the special tool. 
CAUTION: To prevent damage to the axle shaft oil seal, install the Differential Seal Protector before positioning the inboard CV joint housing in the axle.
CAUTION: Always install the halfshaft with a new retainer circlip and a new rear axle wheel hub retainer.
CAUTION: Never use power tools to tighten the rear axle wheel hub retainer.
To install, reverse the removal procedure.

ok then here is the procedure
1 take off the axle nut
2 on the lower control arm you will find a large nut and bolt i belive the nut is a 21mm and the bolt side is an 18mm. this bolt is the one at the knuckle near the brakes. remove it
3 you will need to pull the knuckle out of the way or a helper to pull the knuckle out of the way so you can slip the axle out of the knuckle.( its a tight fit but there is room to slip it out.)
4 use a pry bar to pop the axle free of the diff. hosing its held in by a spring clip make sure the clip comes out with the axle if it gets stuck inside you will have to fish it out.
5 use a pry bar or screwdriver to pry seal out of housing then use a flat object that contacts the entire rim of the new seal so it can evenly be installed with out getting smashed and tap it in with a hammer. ( a good trick here is to use some grease and pack it into the new seal where the spring is this will prevent the spring from being shocked out of the seal during instalation . the spring keeps tension on the rubber in the seal so it stays tight to the shaft it is sealing.)
6 then revers the above steps. also make sure you are using the right gear lube it will most likely be 75w-140 but make sure you check your owners manual will tell you if it doesnt say on the diff cover. you can cause a lot of damage if you put in the wrong thing. and make sure you feel the axle spring clip snap into place.
as a note there are two types of axle seals that are used on these so if the new seal looks different than the old seal then the folliowing will be important to you.the seals on these have been redesigned so if you axle has what looks like a cup or dust cover pressed onto the shaft where it goes into the diff the new style does not use this and it will prevent the axle form going in all the way so the spring clip will not lock in and you will have a leak. so you will have to remove it and install the axle without it.

SOURCE: Rear Axle Bearing
i know for a fact that the bearing comes with the hub., and if the old bearing is badly damage you may need to heat it to remove it from the axel...so this may be a rather big job if your not equipt
with torch or other ...

Yes you can, If you have taken the front drive shaft off, you can even still drive with the CV joint in place till you want to remove it. You may get some vibration around corners till you replace the CV joint or remove it totally.
But if your going to remove it, might as well wait till you have the replacement so you only do the job once. I had a Bad CV joint on a AWD Chevy van and did the same thing so i could still use it, and then replaced the CV joint when the weather got better.
Good luck and hope this helps.
CAUTION: Turning the differential case (4204) or an axle shaft (4234) with the differential pinion shaft (4211) removed will cause the differential pinion gears (4215) to fall out of the assembly and damage the components. CAUTION: Do not damage the rubber O-ring in the U-washer groove. CAUTION: Do not damage the wheel bearing oil seal (1177). CAUTION: Never remove the wheel bearing oil seal (1177) by itself. Always remove the rear wheel bearing (1225) and the inner wheel bearing oil seal at the same time.
