I tried everything I could think of. Problem is the truck is my daily driver so If I try something and it doesn't work I have to be able to make the truck drivable again the same day. Having a second set of LCA's ready just in case is worth it for peace of mind.
soak the bolts twice a day every day with PB blaster till your ready to remove the arms. that should free them up. had to do this on my jeep before doing the lift. if your worried about braking a bolt get a spare set of arms just in case.
I've been soaking them in PB blaster, not twice a day but I've done it. I'm not worried about breaking a bolt, I'll be replacing them with cam bolts anyway. I'm worried about messing up the bolts so bad I can't even get the nut back on or breaking the rubber in the bushing and still not being able to get it out. Then I'm down to a motorcycle or garden tractor, neither of which will get me to work.
