I had a terrilbe time with just changing one hub. I couldn't even get the calliper mount off... the bolts were killer. I finally bought a better socket (less sides) and it came off with great leverage and PB blaster.
Then the assembly could not and would not come out. I got a slide hammer from auto zone and the thing came apart instead of out. I put the bearing bolts back in and attatched the slide hammer 1 at a time and got more of the hub out. THen I used a hammer and screw driver to "chisel" the rest out.... after 12 hours over 3 days, sunburn, and bloody knuckles I finally changed the hub.
I held my breath that the lights would go out and that everything was working perfectly.... and it was!!!!
I was grateful for the experience and the fact that the other side had been changed by the previous owner/dealer.
I don't mean to scare anyone away but you should know what could happen especially if you are a novice like me.
