To start, I do not have a Jag. I have an 02 Lincoln LS, but because of my activity here, and the similarities between the cars I figured posting here would be ok. Here is my thread on the other site:

Ball joint and another problem, and yes I already searched - Lincoln vs Cadillac

So, I am still confused about a couple things. How do I test the rear wheel bearings? Also, do you guys have any other ideas about what could be going on?

Thanks guys!
