The Stovebolt Site Forums The Shop Area Driveline 1947.2-55.1 One Ton Rear End Upgrade - New Tech Tip

I don't think you will want to bother with the felt as that part is not needed with the new seal. Also the torque specs for the big nut are 160 ft/lbs to 280. So the procedure is to torque to 160 and then apply more to get the hole for the cotter pin to line up with a slot. I used a six point socket and I had to grind the outside to make it fit.
