Detailed Description

Dana Spicer FSGR 42500 is a front drive axle shaft seal engineered for specific Jeep front axle configurations. It is listed for 1984-2001 Jeep Cherokee, 1987-1995 Jeep Wrangler, 1993 Jeep Grand Wagoneer, 1984-1991 Jeep Grand Wagoneer, and 1986-1992 Jeep Comanche when equipped with a Dana 30 axle and reverse rotation. This makes it a direct-fit sealing component for Jeep Cherokee front axle seal replacement, Jeep Wrangler Dana 30 front axle service, and other matched applications using the same axle setup.

Spicer positions this part as an OE-level replacement, meaning it follows the same standards used for original equipment axle components. The rubber seal material and specified inside diameter help maintain the sealing interface at the axle shaft, supporting proper lubrication retention and contamination control in the front axle assembly.

Common Issues This Seal Addresses

• Front axle gear oil seepage at the axle shaft seal area
• Contamination entering the axle housing through a worn seal
• Leak-related fluid loss around the Dana 30 front axle shaft
• Seal wear from age, heat, and drivetrain use
• Service replacement during Jeep Cherokee, Wrangler, Grand Wagoneer, or Comanche axle repair

Installation Notes and Tips

Verify the axle configuration before installation. This seal is listed for front position use with a Dana 30 axle and reverse rotation, so matching the axle type is essential for correct fitment. Inspect the axle shaft sealing surface, housing bore, and surrounding components for wear or damage before installing the new seal.

Clean the sealing area thoroughly and confirm the seal seats evenly during assembly. For Jeep Cherokee, Jeep Wrangler, and related applications, confirm the vehicle year and axle details against the fitment listing before ordering or installation.

Quality Assurance

Genuine Spicer light vehicle axle products are manufactured to OE standards because they are OE parts. Dana Spicer continues to develop axle and driveline components to maintain the performance and reliability expected from original equipment replacement parts.
