Looking for a good source of info for rebuilding my 14 bolt FF , other than Billavista's article on Pirate 4x4 or the military manual that he has in that article. I says in the military manual that the pinion support bearing has to be installed with the part number facing the front of the truck. I was wondering why? I installed mine last night and I'm not sure which way I put it in. I'd go look , but I'm at work.
