ok.... jack up by axle
remove wheel
remove axle nut
remove hub, NOT WITH A PULLER, you may pull the hub apart... Back the 3 bolts (which you have removed, and should replace for these steps) out so the head is about 1/4 inch out. With a loose fitting socket, or a centerpunch, knock the bolts back inward to knock the hub out of its seat. as the head meets the surface, back the bolts out another 1/16 to 1/8 inch... when you have it far enough out, a wedge type tool may be beneficial to you in pulling the hub from its pressed seat.. once it is knocked loose, remove the bolts, and you will be on your way..
then out comes the axle... get the axle in a vice, then pop the inner clips out with a screwdriver and hammer... then pound the joints out... then the new ones back in... make sure it is greased up good... make sure it moves nice...
put everything back together...
then the MOST important part.... go test them out... get yourself into some mud, rocks, hills, anything that you could do to make us proud
