Spicer Rear Axle Wheel Bearing & Seal Overhaul Kit for 2007-2017 Jeep Wrangler JK & Unlimited (Both Sides)

Eliminate harsh rear wheel end vibrations, stop gear oil leaks from ruining your brake shoes, and restore quiet, dependable rotation to your rear assembly with this genuine Spicer Rear Axle Wheel Bearing and Seal Overhaul Package. Specially compiled to service both the driver and passenger sides of 2007–2017 Jeep Wrangler JK and JK Unlimited (2-Door & 4-Door) models across all trim lines (including Sport, Sahara, and Rubicon), this complete master bundle delivers everything required to refresh both rear wheel stations simultaneously.

On semi-floating rear axle configurations—like the standard Dana 44 found on the rear of most JK models—the wheel bearings bear the combined weight of the vehicle, heavy overland gear, and intense lateral trail loads. Over time, large off-road tire leverage can cause pitting in the bearing rollers, while trail debris can score the elastomeric lip of the axle seals. Failing assemblies typically present themselves via an audible roaring or grinding noise from the rear end, or visible gear oil weeping down the inside of the brake backing plates.

This original equipment manufacturer (OEM) bundle eliminates the hassle of tracking down individual wear items by gathering all the critical press-on hardware together in one package. Sourcing genuine Spicer components guarantees exact matching hardness metrics and dimensional tolerances, preventing premature mechanical failure and maintaining an airtight fluid barrier within the axle tubes.

Kit Highlights:

• Complete Dual-Side Overhaul: Packages 2 premium heavy-duty tapered roller bearings, 2 outer axle shaft oil seals, and 2 mandatory press-on locking retainer collars to fully rebuild both rear axle stations.

• Genuine Spicer OEM Quality: Manufactured by the original equipment supplier to strict structural and hardness tolerances, delivering greater fatigue resistance than generic aftermarket alternatives.

• Premium Multi-Lip Seal Design: Features heavy-duty oil seals engineered to handle continuous high-speed rotation while isolating internal gear oil from outer trail contaminants.

• Exact Dimensional Press-Fit: Case-hardened steel locking collars provide an absolute, slip-free retention force on the axle shafts to secure the bearing pocket geometry.
