Tried some WD40, tried some PB Blaster, and its still tough as nails to get out. Do I just keep spraying the **** out of it with PB Blaster and hope that it loosens up, or is there anything else you guys have to suggest?

Oh, and I do have the entire spindle assembly off the car.

 

put a closed end wrench on them and hit with a hammer.

 

use a johnny bar, or heat. just watch you don't damage the caliper or break the bolt

 

I used an impact driver the great neck one from autozone worked. The top pops off to have a 1/2" drive toss a socket on there and grab a sledge and start wackin lol

 

heat is your best friend
and your worst enemy if you use it wrong.

 

18" Rachet. Works everytime.

 

Torch the SOB!

 

get a metal pipe slide it over the rachet end, will work for sure

i have a 20" or so piece of metal pipe in my shed thats helped me get 100's of stubborn bolts, works everytime

 

+1 for added torque bars, also you might want to try some heat.

 

I snapped mine when I used heat and a breaker bar. The salt they use here in the winter is not kind to bolts. I tried using an extractor with no success, so I bought a used knuckle and new bolts. I also put liberal amounts of anti seize so it wont be a problem in the future.
