Spicer Front Inner Axle Tube Seal Kit for Jeep YJ & XJ (Dana 30 Disconnect / CAD Style)

Keep your front differential gear oil isolated and protect your internal components from trail debris with this genuine Spicer Front Inner Axle Tube Seal Kit. Specifically packaged for Jeep Wrangler YJ and Cherokee XJ models equipped with a Dana 30 vacuum disconnect front axle (also known as the Vacuum Control Axle Disconnect / CAD setup), this service kit includes the specific internal seals required to restore leak-free performance.

Unlike standard non-disconnect housings, the CAD-equipped Dana 30 front axle features unique internal sealing positions to accommodate the passenger-side multi-piece sliding axle shaft mechanism. Over time, heavy trail use, high mileage, or shaft movement can compromise these specialized internal seals, causing gear oil to escape into the tubes or pool near the CAD housing. This premium replacement kit restores original equipment integrity using trusted Spicer OEM engineering, ensuring a precise factory seal lip fit and maximum resistance against fluid breakdown.

Kit Highlights:

• Disconnect-Axle Specific Configuration: Contains the matching internal differential oil seals explicitly engineered to fit the unique driver and passenger-side placement requirements of the Dana 30 CAD housing.

• Genuine Spicer OEM Quality: Precision-molded from heavy-duty elastomeric compounds designed to withstand continuous heat, friction, and aggressive gear oil additives.

• Essential Drivetrain Service: Highly recommended whenever replacing inner axle shafts, servicing the vacuum shift motor, or refreshing differential gear sets.

• Direct Drop-In Maintenance: Eliminates messy leaks and maintains proper fluid levels around your ring and pinion with zero modifications needed.
