So I'm doing the ball joints on my C10 (along with idler arm, tie-rods, pitman arm and shocks) I've never done a 2wd with coil springs. I was reading the book, it says to use a coil spring compressor for safety. Is this really nessesary, I've got a pretty good tool aresenal, but a coil spring compressor is not part of it. I mean, if there's a good chance the thing will come popping out of there, and get me, then I'll have to go get one, but the book also says to disconnect the negative battery cable before the job as well, so I think they err way on the side of safety. And, if I get the jist of the book right, your supposed to support the lower a-arm with a jack? (truck is already supported by frame with front suspension hanging), and then use that special tool (I made one out of a nut bolt and cheap jap extedned socket) to seperate the tapers from their seats, this is the point I would suspect the coil spring could do some damage? THanks for any help!
