if your rotors are worn it's nice to do them, as you have it all part then.
You will need;
54 mm hub socket(snap isn't too expensive and its a good trail tool).
brass drift, big and heavy.
3lb sledge hammer
various sockets.
10mm flarenut wrench(rusty brake lines)
snap ring plier, the kind with flat surfaces that spread open a snap ring.
That's the min items.
Basically you pull the hubs off, brake rotors, and remove the wheel nuts...etc. Good write ups in the mud tech area.
4wheelauto has some good kits for about 225 each.
I did my brake pads/rotors, wheel bearings with new, inner axle seals, new felts, new pinion(king pin) bearings,....
It's a full weekend job. My cruiser was rusty, cone washers were stuck hard, and it was messy. But when I was done I felt very intune with my truck.
Now I just want to be out of tune with my truck..
