There are two seals for each 1999-2004 Ford Super Duty® Model 60 front inner axle shaft. QU40244 is an oil seal that seals between the differential housing and inner axle shaft. QK4644 and QK4807 are Kits that make installing the two included QU40244 Axle Seals quick and easy, plus the tools will not damage the somewhat fragile oil seals or your axle housing. QU40243 is an external dust seal that helps keep crud from entering the axle housing tubes.
