I realize this sounds like a silly question, but I always struggle in taking off axle nuts that were put on by the factory. One of the biggest problems is how it is crimped on. Right now I need to take both axles off, and it’s holding up me getting the engine out. Both axle nuts are crimped, and I’ve tried multiple methods to un-crimp it. I attempted using a hammer and small chisel to pry it open, but that didn’t work. How do garages (or people more proficient in working on cars) do this? I imagine it’s necessary to un-crimp the axle nut even if I had a very strong impact gun, no? I also wouldn’t imagine there are any special tools other than what I’ve been using, but then again I’ve also thought this before when performing various jobs on the car. Any recommendations other than hit the chisel even harder if that’s possible?

Thanks!
