Perfect fit, 05 F150, 4.6L 4x4 Pinion
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!
Most Liked Negative Review
Don't Buy
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.

It Leaked
Staff Reviewer -
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.
Bottom Line No, I would not recommend to a friend
