Pita spindle nut!

I'm rebuilding the front end on my 01 dodge ram 1500 I have had bunch of problems out of it so I decided to replace everything new hubs new u joints new ball joints, tie rods, shocks, coil springs, axle seals, steering stablizer, etc pretty much everything except the housing itself. On the drivers side the spindle nut is being a pain I cannot break it loose so far I have broke 3 1/2 inch breaker bars a 25" a 24" and a 18" and a 1/2 ratchet. I ordered a 3/4 breaker bar as well as a new 3/4 socket if that doesn't work idk what I'm gonna do. I have tried heat, lube, heat with lube, lube with heat, pretty much everything I know to do I cant get it to break loose lol.
