Mark,

I think we're all still guessing at the problem rather than having the full facts.

I presume that after doing the alignment check, they gave you the printout showing the toe, castor and camber setting for each wheel, including the front to rear alignment? If they didn't. I seriously suggest that you go to someone who has a proper Hunter alignment bed or similar and get a proper check and set of printouts. An example of the sort of printout that you should be expecting to see is in attached pic.

The shop doesn't need to be proficient in XJS adjustments. At this stage, you just want to know exactly what is the alignment spec of your car. I really wouldn't be throwing money at springs / shocks etc just because you had some strange wear pattern on your old front tyres.

Good luck

Paul

Things can be deduced from the wear pattern itself.

Which edge, inner or outter.

Regular or 'cupped"

And, a talented nd across the tread. Point edge of the wear point in or out?

Indeed, it is not exotic in theory/ Unegual length arms, upper and lower. Coil springs.
Shock absorbers. "dampeners" within the coils. Ball joints top and bottom. Adjustable camber, caster and toe.

Aye, Jaguar special tools. As I get ti, to lock the suspension at a given point and then adjust to spec.

Then spec is a topic. As camber varies as the suspension moves up and down, perhaps caster and a bit of toe as well. So, spec's accommodate that.

A good shop will check load. Boot full of load or in the cabin !! And for sure proper tire pressure.

And, my idea is that once a tire begins to wear unevenly, no amount of alignment will stop it from continuing to wear in that manner.

Default Caster adjustment

My 1998 XK8 has wear on the inside of the front tires.The guy at the alignment shop said that the Camber was a couple of degrees off. He said that I needed a Cam Bolt for adjustment. I believe that it is good for only.15 degrees. I have 14" from center of wheel to Fender. I know that it needs to be 15 3/4". It seems like I need two front springs. My question is that they sell new lowering springs that I may find that it would drop down an inch and half. wouldn't I still have the same problem that I have now?
