Lower control arm outer bushing shell removal frustration...

I used a reciprocating saw to cut a seam in the outer bushing shell. I know it's dangerous and can leave a groove in the outer bushing surface on the LCA if you are not careful, but I took my time and it worked for me. Once you have a deep enough groove, it is easy to use pliers/chisels to collapse the bushing shell in on itself.

Pictures would probably help us devise a better strategy though. Good luck!
