Xk8 rear wheel bearings

Are the rear wheel bearings adjustable on my 2002 XK8 as I have play in them no noise

Are you sure its the wheel bearings and not play in the U/js, diff output shaft bearings or lower fulcrum bearings?
Generally if the bearings have play they need replacements, there is a spacer in there but I have found the new bearings go in without needing to change anything.
