A quick overview for ya....
0.) put vehicle on jackstands, remove wheels, drums, take off cover, drain, blah, blah, blah.
1.) remove the cross pin retaining bolt (this is a small wrench, like 5/32s or something), slide out the cross pin.
2.) now the axle shafts will push in slightly, enabling you to remove the c-clips.
3.) rotate the carrier around and the top spiders will slide out then enabling you to remove the side spiders.
Thats all there is too it, sounds simply eh?
You shouldn't need much more than a simple set of sockets/wrenchs. The of course gear oil and RTV to seal it back up.
