I've found a problem with my rear pinion yoke. A new one is on the way along with a new seal. I've searched here and elsewhere and am getting a host of conflicting information. My Haynes book says to torque to 17 ft/lbs in the specs. Then, in the instructions, it says to check what the preload is and to set it at that level plus 5 in/lbs. Having no idea what they are talking about, I searched. I have found several sites that start at finger tight plus 1/16 of a turn to 150 ft/lbs. I know the actual setting is somewhere in between, but haven't got a clue as to how tight to torque the nut. Any help? Also, what's the difference between the preload and the torque?
