I've got a set of extended Upper Control Arms to address my camber issue. To get extended an inch gets welded in and braced, but kept to look original. The guy who did it in Cali was awesome. But he doesn't remove ball joints or cross shafts so they now need to be replaced. New ones on the way as we speak. So cross shafts, no problems, all of 10 mins and they are out. Upper Ball Joints. Wow. No go. I've replaced the lower ones in the past and had to source a 2nd hand socket (easily biggest socket I've ever bought) as they are screw in. Those came out really easy. The uppers, as you can see in the page from the chassis manual below, require a snap on socket or a 1 7/8" socket. I was able to get a 1 7/8" one locally. Unfortunately it is not a perfect fit, it does have an ever so slight movement in it. So tried it on both, just slips off and has started to "round" the edges. Let em soak overnight with penetrating oil thinking they may be seized on, still absolutely no movement. So that said does anyone have any guidance on how I get these out. I don't have the new ones yet so I'm not 100% sure how they go together and can't find any pictures online. I'm assuming it's like a lock nut though. I should be able to undo it and the ball joint should then slide out the bottom. I've tried heat on it as well, I don't have an oxy/ace torch, but it is an oxy/MAPP. It's not quite as hot as oxy/acc but close. Tried that, got one pretty hot (glowing), still no movement. I hate to say it but I am thinking cold chisel Thanks in advance for the guidance / advice / tricks.
