So after rebuilding the front end of my 92 completely, I knew it would take more than the usual toe jockey to get it aligned correctly. Found a chassis specialist who claimed to have experience with these cars so I put it in his hands.
He called and said he’d gotten it set up, so it would not wear the tires, but could not bring it into specs [he mentioned to upper ball joint shims] because it was “a 30 year old car and things just wear”. Considering that I replaced everything except the cast parts [upper and lower control arms, and shafts] that did not look like they needed replacing, I was disheartened. Asked if the problem was the way i put things together and he insisted it was not.
The fellow was old-school and didn’t trust the new machines. This meant he could not see the results of adjustments in real time and since things are so interdependent I suspect it would have taken him years to play with various shim combinations given the equipment he was using. He’s a very nice fellow and I’m sure he did his best, but I am not sure how the car is going to drive when I pick it up tomorrow.
The dealer already told me they don’t work on anything older than 95.
If anyone knows of a shop with extensive Jag chassis experience in SoCal, please let me know.

 

Only two adjustments possible on the front - one uses shims, these don't wear and set only caster, there must be exactly 4 on each side, never less, never more and they are distributed front to rear as needed on the top ball joint.

Did you replace with new joints and mounts or re-use (bad idea) - sounds more like new school not old school there's no real time on these cars - set, assemble, measure, disassemble, reset, assemble - rinse and repeat, on the front there are only 4 permutations - the shims are all the same there are sizes as such.

This may sound nuts but you absolutely could do this yourself if you've managed to replace all the joints etc - search for a camber / caster gauge and check out the notes of our resident Guru Grant Alignment.

 

I have heard about RMB in North Hollywood. No connection but have heard some members here us them. Lots of Jags of all types there.
