Torque specs on the AXLE SHAFT nut is VFT (very ****ing tight).
Check your door jam for the date of manufacturing, I'll bet you have a early model 2001, which would explain why you dont have vaccuum hubs.
As for the hub assy, it's as simple as having the correct size socket for the shaft nut w/ an impact gun, a 12 point socket for the hub bolts, a BFH (big ****in hammer) for knocking the old hub loose, and all the random tools for removing the caliper & bracket.
Also, if you're lifted, I would suggest staying away from remanned hub assys. Get new ones preferably OEM, Timken, or Moog ONLY. Double check to see if you have front ABS when you order or you will recieve the wrong parts.
