Spicer Front Inner Axle Shaft Oil Seal for 1998-2004 Ford Super Duty F-250 to F-550 (Dana 50 / 60)

Stop annoying front axle puddles, maintain critical differential fluid levels, and protect your vehicle's drivetrain with this genuine Spicer Front Inner Axle Shaft Seal. Specifically engineered to fit deep inside the axle housing tubes next to the differential carrier, this high-integrity seal is the definitive original equipment replacement for Dana 50 and Dana 60 solid front axles on classic Ford Super Duty trucks.

On heavy-duty 4x4 platforms, the inner axle seals act as the primary fluid barrier for the entire front differential center section. Over high mileage, or during rough axle shaft installations, the delicate rubber sealing lips can easily slice, tear, or succumb to thermal hardening. A failing inner axle seal typically presents itself through gear oil weeping or dripping out of the ends of the front axle tubes near the steering knuckles. If left unaddressed, a low fluid level in the front pumpkin will rapidly overheat and destroy your expensive ring and pinion gears and carrier bearings.

This original equipment manufacturer (OEM) replacement seal features a premium rubber compound and an integrated guide sleeve or heavy-duty casing. Sourcing a genuine Spicer component ensures identical dimensional tolerances and sealing lip tension, preventing fluid leaks and keeping trail dust safely locked out of your differential fluid.

Kit Highlights:

• Genuine Spicer OEM Quality: Manufactured by the axle's original equipment provider to guarantee matching factory rubber durometer and exact dimensional fitment.

• Premium Oil Barrier: Formulated to withstand intense differential fluid temperatures, maintaining a tight elastic seal against the spinning inner axle shaft journal.

• Prevents Costly Differential Failure: Replacing a weeping inner seal early keeps your gear oil trapped in the center section where it can continuously lubricate the ring and pinion.

• Heavy-Duty Construction: Built with a rigid outer steel shell to ensure a secure, spin-free press-fit inside the front axle housing tubes.
