Lower control arm outer bushing shell removal frustration...

So I tried welding a washer to the outer bushing shell and pressing it out...Twice. Both times the welds pulled chunks of the bushing shell off with the welds, so now there's not much of a rim left to weld to. :wack: Any other suggestions? How thick is the metal in the walls of the bushing shell?
First remove the pin and the rubber from the outer portion of the bushing.Once these are removed, roll outer edge of inner inward and cut it down with a panel cuter about 2/3 or more if needed down into control arm. This will allow you to remove it. The cutter can be used with air tool or hammer stile if no air. The inner can be removed from the pin by hammering on it. This will expand the metal and it will just slide off. If removal dose cut into the control somewhat, just clean it up with hand grinder so it will not damage the new bushing when installing. don't use any lube on new parts. Have replaced many this way. It's quick, easy and gets the job done with no fuss. Good luck. Jack Arnew Suspension Systems
