Well after finding out that my diff was bad at 42k miles, i had to do something i was not really wanting to do. I sold my XK and bought a Ford F150 supercrew cab xlt 4x4 offroad. I really like my XK, but I just could deal with with everything breaking on it. The rotors were warped and there was a sound from the front tight that sounded like CV problem. Thanks for all the help guys and I will still read the forums from time to time.
