Aligning the rear wheels? Service guy says impossible...

Is this something reasonable to go back to an alignment shop for adjustment? Will they typically be familiar with shim-based adjustment? Any diagrams for the toe/caster so I can just point to it for them? If the car drives fine, is this worth bothering over?
They said something about having a solid rear axle with nothing to adjust... It seems unthinkable that Jag would stick a rear live-axle on a VDP...

Either the shop knows nothing about Jaguars, or did not even look at the rear suspension.
If you only got charged for a front alignment, then the rear alignment would be an extra charge anyways.
Why go back to a shop to do work that they do not know how to do? That would only make things worse.
The rear alignment seldom needs actual adjustment. If it tracks well, and there is no obvious uneven tire wear, then you may leave well enough alone.
Very few non-Jaguar shops will be familiar with the shim based camber adjustment. Indeed, even Jaguar dealers may not like to do them as it involves trial and error as well as undoing the axle shafts.
BTW, even front end alignment is not a maintenance item. You only do a wheel alignment when it is required.

THERE IS NO CASTER ADJUSTMENT IN THE REAR. LIKE BOB SAID ONLY CAMBER AND TOE. AND THE TOE IN THE REAR SHOULD ALWAYS BE CHECKED AND ADJUSTED BECAUSE IT AFFECTS THE FRONT SETTINGS. YOU SET REAR FIRST AND THEN THE FRONT. ON THE CAMBER, IT REALLY DOES NOT NEED TO HAVE SHIMS INSTALLED UINLESS ITS ABOVE A -1.5 OR HIGHER. BUT THEN IF THIS IS THE CASE YOU HAVE EITHER BENT COMPONENTS OR SAGGING SPRINGS THAT DROPPED RIDE HEIGHT. i HAVE SET CAMBER ON 3 REAR ENDS IN 15 YRS IF THATS A GOOD INDICATION FOR YOU AS TO THE NEED.

The factory seems to use the 4mm shim in almost every car. I usually keep a few 6mm shims in stock for the times I need to have the camber adjusted.
Like BRUTAL says, the camber has to be pretty far from spec to cause tire wear or handling faults. I seem to do more 6mm shims lately because the springs might be getting weaker and need the thicker shims.
Things tend to sag with old age???????????

I have a photo, but do not no how to insert it?
my rear tires have the same wear on each side, the middle to about 2" is worn (flat and smooth). the middle to outside edge has normal wear.
thank you,

is it the same idea on the xj6 for adjusting camber and toe? someone says you have to buy the bolt that adjusts the toe and camber on xj6?
