For what it's worth, I have a looseness in my Jag rear, also. If I grab the wheel top and bottom I can rock the wheel. Grabbing it front to back does not cause any rocking. I greased the Ujoints between the differential and the wheel and the looseness was much reduced.

I am going to replace the 4 universals that drive the wheels ASAP. The Jag uses the ujoints to maintain the camber vertically. I hope this is helpful.
