Most guys I've seen at shops use a cutoff wheel to slice the pitman arm close to the splines ,then a quick blast with an air chisel to finish the "split" and it drops off pretty easily..seeing there is no room for a puller,this is their way to cheat and save time & labor..
I guess some trucks though,dont have enough clearance to get the arm off the box splines and it has to be loosened or removed to get it off and install the new one..
I use that method to split bearing races...
They are not horrible to replace. Just really heavy. It'll just squeeze out past your torsion bars. Always something, hey? I drove the caddy to work today and discovered I have a boost leak. Sounds like someone letting air out of a balloon when it makes boost lol
Probably why your starter died if it is missingLol, boost leak sounds all bad.
Everyone talks about a heat shield that is tough to remove. Not seeing one on mine, probably got left off by the builder.
Will look into a replacement.
