Upper ball joint removal

Upper ball joint removal
I want to change the ball joints in my upper control arms. I'm hesitant to buy a ball joint push/pull kit since I don't see using it often, and I don't have sockets large enough to put my own press together. So I'm going to see if I can get a shop to do it. Question: Does the ball joint get pressed up and out , or down and out? (I'm assuming it is up and out.) I had one shop say they couldn't be removed, but I know they can.
Thanks all!
Thanks all!

Thank you, Michael. That is the best info I've gotten on this topic, yet. I'm surprised to see he job is more involved than I thought. I imagined it could be done with a simple push/pull bush tool. I do have a question, though. On page 8, I can't tell if the special tool is putting its pressure on the ball joint bolt or it's pressing a cup against the underside of the flange? I'm assuming this data applies to the 2005 model, as well. Really appreciate the knowledge.

Hi,
The special tool (essentially just a deep cup):
https://jlrequipment.service-solutio...px?SKU=204-200
will press on the shoulder of the ball joint to push it out once the rubber gaiter and clips are removed.
It's probably easier to see from this image:
...although, in practice, I don't think it matters since you're replacing it.
Special tool 204-199 is just a pair of cups that fit over the new joint ready for the press:

You should be able to find suitable large-diameter sockets in place of these.
Upper ones are straightforward, the lower ones are - er - not so easy.
It's the same part for all MYs. Pop the new joints in the freezer for a day or two before the job.

I recently did my own ball joints, bushes and so on. Just a couple of points on things. The pdf copy of the JTIS tools used shows the wrong tool for the splitter so ignore the top drawing. Secondly, I removed the gaiter from the old ball joint to get a better bearing surface for the socket or press tool.

Perfect Timing
Starting on my front end project Monday so this is a great help. Doing both ball joints and control arm bushings, going to poly. I may try to replace the ball joints myself with a kit but likely turn up going to a good indy shop in town. Thanks for posting this PDF, in will come in handy.

Hi all, on the discussion of ball joints.
I got my 2003 XK8 up on the lift and found my ball joints boots are all ripped. I found the part # for the upper JLM21380. I can't find the part # for the lower ball joint I have seen MNC1350AA posted in other threads but from my searching those fit 97-02, not 03-06. Does anyone know what that # is for 2003+ 4.2 lower ball joints?
