Spicer Front Inner Axle Shaft Oil Seal Kit for Jeep Wrangler YJ & Cherokee XJ (Dana 30 with Central Axle Disconnect)

Stop front axle fluid leaks, protect your internal engagement mechanism, and maintain critical gear lubrication with this genuine Spicer Front Inner Axle Shaft Oil Seal Kit. Specifically bundled to service Dana 30 front solid axles equipped with a Central Axle Disconnect (CAD) system, this package completely refreshes the primary oil barriers on your vacuum-disconnect Jeep.

On vacuum-disconnect front axle configurations, the sealing layout is unique compared to non-disconnect models. The driver-side seal is pressed deep inside the center section pumpkin next to the differential carrier, while the passenger-side oil seal is located directly to the outboard side of the shift-fork disconnect housing. Over decades of trail use, continuous engagement cycling, or rough axle shaft installations during a U-joint replacement, the delicate rubber sealing lips can slice, tear, or harden. A failing seal will typically announce itself when gear oil begins weeping or dripping out from the center-right disconnect shift-motor housing or the ends of the front axle tubes.

This original equipment manufacturer (OEM) replacement bundle includes both premium rubber-encased oil seals to properly overhaul the vacuum-disconnect housing configuration. Sourcing 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 two-piece passenger axle shaft journals.
