I have an 04 4x4 5.4L. It has the limited slip rear end wich I do understand that there will be a little rear end tire hop when making sharp turns. But for the last few weeks it seems to be getting worse. When I am stopped and then turn right or left the rear end hops pretty bad. I cannot see anything that is broken or loose underneath. Could it be that my tires are starting to weaar and it causes it more?

Any ideas????
