rotor and wheel bearing replacemet on 86 k10

[ol yellow 72]

hey guy new to the 73-87 side been on the 67-72 side for years, but i just bought a 86 custom delux 4x4 swb today and the rotors are warped bad, and the wheel bearing seem to be bad. could someone please guide me on how to remove the lockouts, and access the bearing. Also guys at Autozone tell me that the rotors are slide on, is this true? because i thought the were bolt on.

im gonna tear into this as soon as the garage heats up nice tonight so help asap would be great.
