Thank you K5lwq,
I was aware of an upgrade, I have not upgraded though.
I did do a cheat, several years ago, I added a washer under the nut, which removed most of the slop for a while anyway.
I really need both sides, Thanks for the link.
I may take the ball joint to some auto parts suppliers, if I could get the correct taper, I may be able to do a bit of cut and weld…
