Spicer Front Inner Axle Shaft Oil Seal Kit for Jeep CJ, YJ, TJ & XJ (Dana 30 Non-Disconnect, Pair)

Stop front axle fluid leaks, protect your differential center section, and maintain critical gear lubrication with this genuine Spicer Front Inner Axle Shaft Oil Seal Kit. Specifically bundled to service Dana 30 solid front axles without a Central Axle Disconnect (CAD), this comprehensive dual-side package completely refreshes the primary oil barriers on your classic or modern Jeep.

On solid-axle Jeep configurations, the inner axle seals are pressed deep inside the axle housing tubes right where they meet the differential carrier. Over decades of trail use, thermal cycling, or rough axle shaft installations during a U-joint swap, the delicate rubber sealing lips can slice, tear, or harden. A failing inner seal typically announces itself when gear oil begins weeping or dripping out from the ends of the front axle tubes near the steering knuckles. If ignored, the differential fluid level will drop, causing catastrophic friction wear on your expensive ring and pinion gears.

This original equipment manufacturer (OEM) replacement bundle includes two premium rubber-encased oil seals to service both the driver and passenger sides of the axle housing. Choosing a genuine Spicer component guarantees exact factory dimensional tolerances, matching steel support casings, and the correct rubber durometer required to maintain a persistent, leak-free seal against the spinning axle shaft journals.
