nothing super about this truck at all,2002 5.4,4.10 gears,just hit 90k, found oil on the driveway,is it the wifes honda minivan,nope its the ford,of course. leaking from driveshaft input to the rear diff. Can anyone tell me what this repair involves? just for fun I thought I would list the repairs I have done since I bought this truck for 20k at 64kmiles..... exhaust mani studs rotted off, spit a spark plug just as I was hooking up the plow, brake line burst where it was rubbing a wire bundle, drivers window loose in its frame,replaced 3 coil on plugs, this thing is about equal to the 69 triumph tr6 I had,actually it might be worse
