Got a buddy with a 05 6.0 that is on the rack right now. Dealer is replacing the rear main as it is leaking. He loves his truck but they have had his trans out three times before they got it right. Now after all of that oil starts showing up on the floor of his shop where he keep his truck. (You can eat off this floor) He's not to happy right now with all the inconveniences but he loves his truck.
