  • Rear Axle: Pinion seal

    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

        One more thing, as you torque rotate yoke, if it gets hard to turn it could be too tight. 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.

ID:	1716123Guessing this being towards outside with yoke resting against indented surface

              Ditto; do not put slinger in backwards or it will sling oil out rather than back in. The convex part goes toward the the differential. As always, my sage advice comes with a double-your-money-back warantee.

                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.

                  Convex: arched up; bulging out. So to be finalized, the raised part goes in first towards differential...Yea, I get it now, Right?

                      This sure reinforces the decision I made to have mine done professionally...and it really did take him only 45 minutes...and cost me just over $100.

                        Maybe so but I like to get my hands dirty every now and then, and believed I learned something...with a little help from friends here.
