I'm not sure it can be corrected, easily. There does not seem to be any way to adjust the toe on the rear wheels without doing some major bending, and then it'll be a total crap shoot as to how much I need!


I think I'll attempt to adjust the rear camber and see what happens.
Rear castor adjustment must have only been released on the XJ40 there is an eccentric on the lower control arm fulcrum shaft on the hub carriers I have. These fit the XJS except the XJ40 fulcrum shaft is thinner.

How are your wheel bearings?

Have not considered it, but the rims are far from showroom quality. It very well could be the issue.


Thanks for bringing this up.

Good luck

I've tried to pull on the wheel when jacked up in the air, and I feel no wobble at any angle, so I think they're ok.

If there is no play in output shaft bearings or universal joints it is possible for everything to appear ok when pulled on but still have bad hub bearings. You need to try to move the wheel in relation to the hub carrier. ie restrain one and move the other.
Not saying it is the case here but a quick shake check can be deceptive.
