Bhooper,
Not sure if you have a 4x4 or 2wd (you should create a signature with all your vitals), and the two are vastly different. I have a 98 2WD so I'll describe the procedure I use.
1) remove the wheel
2) remove the brake caliper
3) remove the dust cap
4) remove the cotter pin and loosen the spindle nut
5) remove the outer bearing
6) remove the rotor/hub
7) knock out the inner bearing/seal
8) clean the spindle and clean and dry the bearings with compressed air (but don't let the bearing spin at high speed while drying it)
9) pack the inner bearings with grease (if you don't have a bearing packing tool it's a messy job to do it by hand the right way. Put a gob of grease in the palm of one hand and then with the bearing in the other hand work the grease into the bearing until it oozes up between the rollers)
10) after the bearing is packed, liberally coat the outside circumferance of the bearing with grease
11) insert the inner bearing into the hub
12) install a *new* wheel bearing seal
13) pack the outer bearing and coat the outside circ.
14) insert outer bearing into hub
15) reinstall the hub/rotor assy onto the spindle being carefull not to damage the new seal and kind guide the outer bearing onto the spindle so that it doesn't fall out on the ground
16) reinstall flat, keyed washer and spindle nut.
17) tighten the spindle nut to approx. 40 ft/lb (I think) - this is to preload the bearings - then carefully back off the nut till it's loose, then snug it back up finger tight.
18) install a *new* cotter pin
19) reinstall dust cap, brake caliper and wheel
Others may have their own methods, but that's how I did it. But, like I said, if you have a 4x4 it's way different. In fact, I believe the 4x4 has sealed bearings that can't be repacked, and if you replace the sealed bearings you may need a press to R&R the bearings and a *BIG* torque wrench for the spindle nut.
