Make sure you can seat 3/8 drive into the fill plug and make sure you can turn it out easily. You really don't wanna do all this and lastly find out you can't fill it back up.

Take off :
Wheels
Brake hardware.
Push in the axles.
Remove C clips inside the carrier.
Pull axles half way out.
Remove Carrier bearing caps. They have to be reinstalled that way. L or R and UP. They must go in the same orientation.
Pull out carrier.
collect ring gear shims.
and bearings.
Roughly that's it.
But to put it lightly your gonna smell like hell and it's not much fun.
If you want a real full length write-up well throw something together later.
