to tak the wheel bearing off you need to remove the wheel & tire (obviously), then the brake caliper and pads, the brake rotor, and then remove the cotter pin and cover with the little shim on the end of the axle shaft. then remove the axle nut with a 36mm socket and some good hard brute strength and maybe some pb blaster or comparable penetrating fluidon the nut and threads. next comes the hub mounting bolts which will require the use of a 12 point 13mm socket. once those are removed you can remove the hub unit. it may tome some force to remove so dont be shy with the bfh. after its out make sure you clean out the hole where the bearing sits inside the knuckle and then lightly coat it with never sieze to make it easier the next time things have to come apart. i'v never had to replace u-joints as ive only replaced cv's with cv's so i can thelp there.
