I let it soak in PB blaster and using a breaker bar. The driver side came off easy so I am guessing Godzilla himself torqued the passenger side down. Any help would be appreciated. If nothing else probably going to have to cut it off at this point.
I had the exact same problem on the passenger side. Godzilla must have assembled my passenger side suspension too. The torque spec for this bolt is high (120ft-lbs if I remember correctly) but it's on there much tighter than that from the factory. Or maybe there's thread locker....

Anyway, get a good 6-pt socket with at least 1/2" drive, a 24" breaker bar, and a propane torch. Hit the nut with the torch to heat it up, then make sure the socket is on the nut properly and pull as hard as you can. It will make a very loud crack when it lets go and it will sound like you broke everything. Make sure you don't slam the breaker bar into your fender when it lets go....

You could also use an impact gun if you have access to one. I didn't when I did this but I wish I did.
