Upper and Lower Ball Joint Replacement

I got them out. Kind of scary with the poorly-sized socket. I had the same experience as you; I needed the breaker bar until the upper was almost completely out. Glad that using heat made the second one easier for you. Do you have the new uppers in yet?
Yes, the uppers went in easy compared to coming out. Still a lot of work tightening them up. I tightened them up as best as I could and then put a torque wrench on them. Each one was about 125 ft lbs like the factory calls for so I don't think they're coming out soon! They are just hanging there now because I just got the lower ones in the mail to put in. I'm pretty sore right now but like I said if I'd have used heat right away it would have went a lot better.
