Spread a rag out to lay out all your parts on and have a couple extra rags handy. Remove the caliper & pads, remove the locking knob, remove the 2 snaprings (big one inside hub and small one on end of stub shaft), remove the lock-in hub internals, remove the spindle nuts (requires the spanner nut socket), pull whole hub assembly off the spindle (rotor and all), try not to let outer bearing fall into the dirt. Inner bearing should stay in place because of the grease seal. Remove spindle and brake dust shield, and by this point you should have a stripped down knuckle. The axleshaft just pulls straight out of the pumpkin. Upon re-assmbly be sure not to over tighten your spindle nuts, they set your wheel bearing preload. One nut has a small stud on it that aligns with the holes on the washer that goes between them. Grease the bearings and check the seals while you have it apart. You know that clicking may end up being the wheel bearing, one of the guys on here Irishman was having a clicking problem from his with the hubs unlocked. There is also another smaller bearing in the back of that hub you should check too.
