A-Arm disassembly - 66 Barracuda

I stripped many of rusted up cars and never once had one the air chisel didn't push out since I started using that method posted above. Swinging a hammer in there is pretty tight. You can use the air chisel at and angle by leaving the nut off part way and putting the tip of the air chisel punch in the nut. The hammering vibration of the chisel itself loosens the bolt in the sleeve

The bolts are pretty hard , If sawing them get a couple of blades and you will need to saw both sides of the bolt. Pack a lunch you'll be there a while if doing all 4 . LOL
