What tool are you guys using for pressing off the LCA outer ball joint from the front 997GT3Cup/RSR wheel carriers? The old style 996 wheel carriers were easy as any basic press off tool would do the trick but the 997 wheel carriers use a design where the outer LCA ball joint nut is buried in the wheel carrier itself. I think Porsche has a special tool for this but I can't find it in PET. Thanks....
It's in every manual/catalog I checked except for '07 & '08 RSR. Look in the accessories and tool section, first page.
The RSR Manual had only one part listed, Cups have each individual piece (3 total) listed. Unsure of the difference.
RSR:
extractor wishbone
997.450.345.9B
Cup:
locating bolt for press-out tool
996.721.920.90
pressure rod for press-out tool
996.721.923.90
pressure piece for press-out tool
996.721.921.90
You can separate the LCA from the upright by smacking the end of a 1" aluminum or brass rod inserted into the the upright to bear on the LCA stud. Make sure you have the LCA nut screwed partially on to protect the stud threads. I grip the upright in the wood jaws of a B&D shop vice, and use a 5 # sledge to do the smacking. I used this method 3 times to change wheel bearings on my previous 997.2 GT3, which had the same/similar front upright to a 997 Cup.

Thank you! I completely overlooked this in the accessories section as it didn't quite jump out.
Factory tool uses the steel half circle as backing, a threaded hex steel shaft is used to press the ball joint pin off of the upright. Turning the hex shaft drives the pin out.

Wow, that cost is hard to justify. I've often thought that some sort of tool exchange arrangement for trusted Rennlist members might be interesting. Maybe one in which owners of special Porsche suspension, engine, and transmission tools could post what they have to the collective and make them available. The lending of a tool may involve some modest compensation or perhaps bartering with another tool. I have a few tools that I'd be willing to loan out on this basis, and I'm sure that there are plenty of tools owned by others that I'd like to have access to. A reasonable and modest fee for the service could be negotiated, perhaps at a rate of around 10% of the tool cost, plus shipping both ways.
Of course, this would be fraught with the potential for something going wrong -- such as a tool that doesn't get returned, gets damaged, or whatever. So it would involve some lender/borrower caution, and some protection guidelines to help keep people out of trouble. I don't want to be in the tool rental business, and I doubt others on this list would want that either. But it might work if we had the right attitude -- that a tool exchange would function both as a favor to others, and as a resource that would provide a means to acquire needed tools for our own projects as well as a means to help defray the ridiculous cost of buying certain specialized tools that we may each use only once in our lifetime. If there were such a "pool" it might even encourage me (and others) to invest in a few tools with the justification that the cost may end up being shared. Imagine what sort of resources could be available if we had a virtual "pool" of special tools owned by members in the Rennlist community.
Also, the discussion of tools, sharing aside, can result in a good exchange of information and advice, which is helpful as well, including creative tool "workaround" solutions, such as that suggested by tjsmaryland, above.
Is this too idealistic, or might there be interest in setting up a Rennlist thread to consider this further?

Can the front wheel bearings be removed (using the appropriate Sir Tools puller or similar) without disconnecting the LCA?
