Ford used both one piece and two piece Inner Axle Shaft Oil Seals in closed Knuckle Dana 44 front axles. Dimensionally, the two types are interchangeable and by the early 1970's, all the axles were built with the one piece seal that combines the Seal and Guide into a single unit. I always replace the two piece Seal with the one piece as I believe it has greater sealing ability plus longer life. With a closed knuckle axle, seal seepage from the differential often goes unnoticed until the a catastrophic ring and pinion failure occurs because the errant lube ends up in the knuckle ball. These Seals are tricky to install so I recommend you also order our optional installation tooling. Axle disassembly including differential removal is required to replace the Seals.
