I keep forgetting its the A body forum and not the heavier B bodies. So yes A bodies the control arms likely hold up better cause of the lighter weights. I got a B body..I tried signing up on B bodies but could not?
It's just the ball joint sockets have a strange interference thread that sort of self destructs them if they get changed a lot. And some places are awful rough in replacing them. And you can forcefully install one cross threaded that we be fine for it's life span but when you take it out the threads are toasted for the next install.
Same for bushings too. I've seen gnarly gouges in LCA's from people chiseling the hell out of them trying to get them out.
