ok, i went to the stealership today to get my foglight fixed and was talking to the ford tech about the rear end shutter problem and how i was getting sick of getting the clutch packs greased every oil change. he told me to come back in in a week, apparently ford has come out with some new clutches or something that fix this problem, the shutter on take off, is this true, herd anything about this?

 

I think you are mixing two different problems there bofer. The grease fix is for the driveshaft slip yoke splines coming out of the transmission. The clutch pack fix is in the axle and that has usually been fixed with replacemant clutches.
