Here is a how to on swapping axles:
Jack the car, block the front wheels, and remove the rear tires.
Use a 10mm ratchet wrench to remove the brake caliper
Tie the caliper to the shock mount with a piece of wire to keep it out of the way. DO NOT LEAVE IT HANGING BY THE HOSE
Use a brake spoon to loosen the emergency brake and remove the rotor. After you get the rotor off you need to remove the clips that hold the e brake pads in place. Press in on the holder with a flat screwdriver and slide the retainer out
Remove the brake assembly and set them aside. Now you need to rermove the ABS sensor. Take a 10mm socket and remove the bolt from the back side of the dust shield
Set the ABS sensor aside on the axle and remove the diff cover with a 1/2" socket.
Place a pan under the diff and crack the cover from the bottom to allow it to drain
Rotate the carrier until the cross pin retainer bolt is accessable, remove the bolt with an 8mm socket
After you remove the cross pin retainer remove the cross pin with a blunt chisel and a few light taps with a hammer
Use the retainer bolt to pull the cross pin out of the carrier
You will need an extra pair of hands to push in on the axles so you can remove the C clips. While they press in on the axle use a flat screwdriver to push the C clip out
Here is a pic of the C clip
Loosen the carrier bolts and remove them along with the hardware, and shims. Be sure to keep them EXACTLY in the order they were installed. After you set the hardware aside you can pull the carrier
Remove the axle seals with a small chisel and a few soft taps with a hammer, then install the bearing puller and tighten it down.
After a few slides of the hammer the bearing will come out
Time to get dirty, you will need ALOT of shop rags and several cans of brake cleaner. Clean through the axle tubes into the carrier housing. When things are starting to come clean roll up a towel and use one of the old axles to push it through the axle tubes to ensure all the old grease is removed
After you get the tubes done, clean the carrier housing, and dont forget to clean the axle vent tube. After everything is squeeky clean time to start putting everything back in place
I use a 1-1/4" galvanized pipe cap to drive the bearings in. It fits perfect for both the bearing and the seal. Tap lightly until they are seated
At this point you can install the new axles, reinstall the carrier and fill with new fluids.
When you reinstall the carrier follow the TQ sequence on the carrier caps, cross pin retainer bolt, and the diff cover
