Somewhere here it said 45min job to change differential seal...well it took me 3hours just to get it apart, pipe wrench to hold yoke and impact wrench to get nut off (pry bar and hammer did nothing). Now is where I need help, didn't pay attention once seal was off as to how the gasket and round metal plate came off (behind seal). Used magnet to remove the plate off shaft but don't know which side goes in first, also other posts say nut needs to be torked but don't know how many pounds to seat it at. Oh, and told yoke shaft should have sealer applied before sliding into seal...grease? Please help so I only have to do this once.

The metal washer is a splash guard for the seal, should be installed as in pic #4 , if you look carefully you can see the impression left by the end of the yoke. The washer goes in first, then put a small amount of sealer on gasket and place it on seal. Lubricate the sealing surface and install seal. Install yoke after cleaning sealing surface and torque to 140 to 180 foot pounds per shop manual. Lou Cote

When I did mine, I had to trim a little the outside of the paper gasket that goes under the seal. To do this I simply put it onto the seal and cut the excess material with scissors. I suggest you check this. I used sealer at the back and outside of the seal. Grease goes between the two lips of the seal. It took me almost two days to do this on a lift.
Nice day to all.sigpic

Some pinion seals now come with a band of sealer on the inside, which negates the need for the gasket. The last National seal I installed had that sealer already on it.
