Spicer Rear Axle Shaft Wheel Bearing & Seal Master Kit for 2007-2018 Jeep Wrangler JK (Dana 35 / 44, Both Sides)

Eliminate harsh rear wheel play, stop weeping gear oil leaks, and completely overhaul your rear axle shafts with this genuine Spicer Rear Axle Wheel Bearing & Seal Master Kit. Specifically engineered as a high-durability, complete dual-side original equipment replacement package for 2007–2018 Jeep Wrangler JK models, this master bundle contains all the primary heavy-duty components required to fully rebuild both the driver and passenger side outer wheel ends on vehicles running factory Dana 35 or Dana 44 semi-floating rear axles.

On the semi-floating rear axle design of the Jeep Wrangler JK, the outer wheel bearings support both the rotational torque of the axle shaft and the physical weight of the vehicle's rear end. Over years of daily commuting, heavy towing, or off-road trail riding with oversized tires, the internal rollers of these factory bearings naturally wear down symmetrically. This wear introduces structural slack, which manifests as a low-pitched howling or growling noise from the rear end that increases with vehicle speed. As the bearings degrade, they cause the axle shafts to run off-center, quickly destroying the outer oil seals. Failing seals allow highly pressurized differential gear oil to weep out onto your brake backing plates, ruining emergency brake shoes, contaminating brake pads, and risking catastrophic internal gear failure due to fluid starvation.

Replacing only one side usually means the opposite wheel bearing is close to failing as well. This original equipment manufacturer (OEM) master service package eliminates the hassle of ordering individual pieces or multiple kits by bundling two premium tapered roller bearings forged from high-grade steel, heat-treated for maximum fatigue resistance, and precision-matched to factory tolerances. Sourcing a genuine Spicer bundle ensures a perfect press-fit onto your factory axle shafts, eliminating the risk of loose tolerances or premature component failure. To provide a complete, permanent repair, this dual-side package matches the primary wheel bearings with premium multi-lip outer oil seals, heavy-duty press-fit axle retaining rings, and fresh axle shaft backing plates.
