  Given that I replaced my U-joints less than 6 mos. ago, and after I
removed my rear driveline last night the squeak went away, what else could
it be? Driving with only my front driveline in, has gotten rid of the
squeak (bad noise) and also the thump and settling motion that seems to
eminate from the rear of my rig when getting off my brakes. I must mention
that I am running a C4 so the rear will always be loaded except when in
  Any thoughts?
