Just curious if others are interested in this.
I've been following a guy on Youtube named Ludworks and he just upgraded his Lower Ball joints using the Jaguar #JLM11860.
He mentions, "It fits most models, Vanden Plas, XJ, XJS, XJR, XJ12, etc. I recommend searching using the "XJS" model name, as it should fit every single year of that model and it was fairly popular in the US."
He also starts the video with trying to go with the aftermarket ball joints which is really just an upper with a sleeve and shows why/where it failed.

He must be on this site somewhere but I've yet to meet him - god I have so many questions! Hehe
