        Comments about National Oil Seal:

        Do not purchase. It will leak! Go to a Ford dealer and purchase a genuine Motorcraft replacement by using tour vehicle's VIN to ensure a proper fit. Buying the right part for a few dollars more will save you time and fluid.

            Comments about National Oil Seal:

            After about 50 miles of driving it leaked. This seal was different then the one I took off (after 130,000 miles). The original had an extra grove in it and the flange had a ridge that fit into the grove.

              05 F150, 4.6L 4x4, 8.8 Rear End, Pinion Seal
              This was a high quality seal.
              It is easy to tap in because on the metal ring on the outside of the seal.
              Fit perfectly!

                  No. This is a pinion seal.

                  I think he means YES. This fits behind the yoke in the front of the differential housing. Another name for it is the pinion seal.
