REPLACEMENTKITS.COM Rear Axle Seal & O-Ring Kit for Ford F250 F350 Transit Excursion — Single-Wheel, OEM-fit Leak Repair

This REPLACEMENTKITS.COM kit supplies the axle seal and matching O-rings compatible with Ford F250 and F350 Super Duty (1999–2024), Transit 150/250/350 (2015–2019), and Excursion (2000–2005) single-rear-wheel models. Built to match common OEM replacement part numbers, the set lets you refresh the rear axle sealing surfaces without hunting down individual pieces. The components are supplied by an American-owned company focused on dependable aftermarket parts and straightforward installation.

How will this kit stop axle leaks?

The seal and O-rings in this kit replace worn sealing surfaces that allow gear oil to escape around the axle. New elastomer seals compress and seat properly against the hub and housing, while correctly sized O-rings prevent leak paths at mating surfaces. Replacing both elements together ensures a complete reseal instead of a short-term fix.

• Includes axle seal sized for single-wheel Ford rear hubs.
• O-rings match OEM contact points to eliminate gaps.
• Replaces multiple Ford part numbers for broad coverage.
