I'm not sure that the upper ball joint can be replaced without replacing the whole control arm. They are not pressed in from the top. they appear the be cast into the arm as one complete assembly.
It's $100 more for the JBA arms, but if you are lifted, & you have to repace the arms anyway, the it's worth it. Even though they are more, this is the most economical time to get the JBA's. But it you can't swing it, JBA also sells Moog replacement arms, which appear to have replaceable ball joints:
http://jeepinbyal.com/SearchResult.aspx?CategoryID=3They are not cast. They are pressed in. take the whole arm off take it to a shop and have them pulled out and new ones pressed in.
the arms are cast iron and the ball joints are not.
ALL ball joints are replaceable. just depends on how much of a pain in the @$#% it is to do.
You're taking me too literally. I try not to write a dissertation everytime I post, so I write with the assumption that if people are talking about ball joints & control arms, they have an idea of what they look like.
If you know from personal experience that the ball joint assembly can be pulled out, & NAPA has an aftermarket ball joint that can be pressed back in... well, you should have said so!:)
I'm sure many of us have had someone say "just go down, & have a shop do this and you're good to go." Then find out that it isn't nearly that easy. So when someone says "this is what I did & it worked great", It takes care of any doubt.

I have not had mine replaced. BUT i do know that
all ball joints can be replaced. They are a mechanical part in a cast part, assembled in mexico probrably and shipped as an assembly.
With regards to the uppers and lowers of the KJ, I have been in a napa store and held them in my hand. They have a new one out. more expensive but SUPPOSED to be much better. Many times we are told something can not be done by some mechanic simply becasue he may not have the neccessary equipment or training to do so. OR the whole part generates him more money for the same or less labor than doing it the right way. I promise that any and all ball joints can be pulled and replaced,
IF you have the proper equipment. I know for a fact that MINE can be because I have discussed this with my local napa store in anticapation of future KJ ball joint concerns.
So NO i have not had it done on my 07, had the stealership do the misses 02 under recall. Plan to do mine and her again as needed this way.
Jesus why do some people get so testy on here.
