1999-2004 Ford Super Duty 4x4 trucks with Dana 60 front axles use a two piece pinion sealing system. An outer wiper seal protects the inner oil seal from road debris. The outer seal is the same for all years and models, but the inner seal will vary depending upon the production date of your rig. We stock the outer and both original equipment inner Pinion Seals for your Super Duty® F-250 and F-350 4x4 truck.
