Soak them overnight in penetrant and then use the biggest breaker bar you can find. 36 or 48 inch, usually 3/4 or 1 inch drive.
You could also try cutting a notch and using an air chisel to try and vibrate the rust loose while spinning the bolt.
Remember, left is loose, right is tight.
EDIT: Also, what impact are you using? Cordless half inch? Pneumatic 1 inch? What's its reverse torque?
Also, depending on how parts have worn, you can try using a floorjack under the wheel to try and relieve some pressure on the bolt. Not a lot of lift is needed, but sometimes bushings go bad and the suspension locks its own bolts in.
DeWalt DCF922, 320ft-lbs I will try using the floorjack
Left is loose, right is right. And orientation flips psychologically when the nut points toward the ground.
Not going to say how I learned that the hard way...
I always hated that expression of left is loose, right is tight. Bolt is not a line, it's a spiral.
Clockwise to tighten (numbers on clock go bigger) Counterclockwise to untighten (numbers on clock go smaller)
If that scares you, wait until you find out about left-hand thread bolts. For those bolts, left is tight and right is loose.
