Mine has similar play at 45,000 miles. I did not measure the amount, but I can feel it and hear it when moving the tire up and down. I can see it move in the outer hub carrier, the inner joint in the diff is not loose at all. I seem to remember a limit for outer hub/bearing looseness in the Jag manual, but do not remember the number. Mine has not degraded in 6 years, so I just check it during my Spring maintenance. Also, to feel better, I once turned the engine off while coasting down a long grade to listen for any bearing noises. No growling or unusual noises, so I keep driving. I expect someone will chime in soon with a limit.
