I came across this thread looking for something else, here is my experience with stuck hubs in case someone is trying to do this, as I removed 4 stuck Solstice hubs front and rear:
Rear Hub replacement (after you remove brake caliper and rotor):
1) Remove the axle nut, it's a 36mm nut, I'm sure you can rent these from the auto parts store. My trusty Snap-on impact with a 30 gal compressor removed it no problem (high quality impact gun makes a big difference with crap air supply, got to pulse the trigger though)
2) You screw the axle nut back onto the shaft so the end of the nut is flush with the end of the axle shaft threads (this is to protect the threads for the next step
3) With your steel headed heavy BFH large hammer, beat the axle in until it just moves, stop beating it in. You don't want to bind the CV, so make sure you don't keep beating it in after you initially break it loose
4) Remove the three 15mm bolts holding the hub in
5) With a flat chisel and chisel holder (or vise grip), use your BFH at each ear of the hub. You're prying it between the metal hub and the brake shield. You must equally move around chiseling the 3 ears of the hub, if one ear moves a hair go to the next ear.
*As the hub comes out, beat on the axle nut again to push the splines through a little more. So you're alternating between chiseling the hub off and beating the axle inward.
*Grind / file down the damage from chiseling if you're re-installing the hub
Front hub removal
1) Same thing as rear, except you don't have to deal with the axle.
The axle nuts are 1-time use, I think the P/N is 10289657 as this is what I was initially searching for
