I'm tryinfg to replace the rear backing plates on a 2002 chevy 2500HD 4X4 before I re-intsll the rotors/brakes. Not sure how to get them on/pull the hub apart. I removed the 4 bolts that hold the plate and caliper bracket, but still the hub not moving? any ideas?
These things always stick. Here's my trick to get them off. Get 4 more bolts with the same thread, but much longer. Screw them into the holes, start the engine (DON'T TOUCH THE BRAKE PEDAL), and turn the wheel back and forth. As you get all the way to one side the longer bolts will hit the axle housing and push the hub/bearing assembly out of the knuckle. Snap on also mahes a special tool for this that does the same thing, but uses the factory bolts. There's probably 20 different ways you can rig something up that will work off the same principle. You're gonna have to get creative if you wanna drive it this week.

the hub is seized into stering knuckle..you can try putting a socket or a small 1/2" drive extension between 1 ear of front axle shaft and axle housing and turning wheels all the way to whatever side you have socket in..this will push hub out of knuckle..try doing this both ways with engine running..keep axle nut on shaft

Here's an exploded view, you'll need to pop off the grease cap #6 then remove the snap ring #8 to get the hub off to get the rotor off. Hope it is of some help...pictures always are.
