Spicer Rear Axle Wheel Bearing & Seal Kit for 2007-2017 Jeep Wrangler JK & Unlimited (Single Side)

Eliminate harsh rear wheel end vibrations, stop gear oil leaks from ruining your brake shoes, and restore quiet rotation to your rear assembly with this genuine Spicer Rear Axle Wheel Bearing and Seal Kit. Specially engineered for 2007–2017 Jeep Wrangler JK and JK Unlimited (2-Door & 4-Door) models across all trim lines (including Sport, Sahara, and Rubicon), this premium single-side service kit includes everything required to replace a single worn wheel station assembly.

On semi-floating rear axle configurations—like the standard Dana 44 found on the rear of most JK models—the wheel bearing bears the combined weight of the vehicle 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 seal. A failing assembly typically presents itself via an audible roaring or grinding noise from the rear end, or visible gear oil weeping down the inside of the brake backing plate.

This original equipment manufacturer (OEM) service bundle simplifies your repair by gathering the critical press-on hardware together in one package. Sourcing genuine Spicer components guarantees exact matching hardness metrics and dimensional tolerances, preventing premature failure and maintaining an airtight fluid barrier within the axle tube.

Kit Highlights:

• Targeted Single-Side Service: Packages 1 premium heavy-duty tapered roller bearing, 1 outer axle shaft oil seal, and 1 mandatory press-on locking retainer collar to overhaul a single wheel end (fits left/driver or right/passenger side).

• 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 a heavy-duty oil seal engineered to handle continuous high-speed rotation while isolating internal gear oil from outer trail contaminants.

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