Spicer Rear Axle Shaft Wheel Bearing & Seal Kit for 1999-2004 Jeep Grand Cherokee WJ (Dana 35 / 44, Single Side)

Eliminate harsh rear-wheel play, stop weeping gear oil leaks, and protect your rear differential from low fluid levels with this genuine Spicer Rear Axle Wheel Bearing & Seal Kit. Specifically engineered as a high-durability, direct original equipment replacement for 1999–2004 Jeep Grand Cherokee WJ models, this package contains all the primary heavy-duty components required to fully rebuild a single outer wheel end on vehicles running factory Dana 35 or Dana 44 semi-floating rear axles.

On the semi-floating rear axle design of the WJ Grand Cherokee, 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, highway cruising, or off-road trail riding, the internal rollers of these factory bearings naturally wear down. This wear introduces structural slack, which can manifest as a low-pitched howling or growling noise from the rear end that changes with vehicle speed. As the bearing degrades, it causes the axle shaft to run off-center, quickly destroying the outer oil seal. A failing seal allows 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.

This original equipment manufacturer (OEM) replacement kit features a premium tapered roller bearing assembly forged from high-grade steel, heat-treated for maximum fatigue resistance, and precision-matched to factory tolerances. Sourcing a genuine Spicer kit ensures a perfect press-fit onto your factory axle shaft, eliminating the risk of loose tolerances or premature component failure. To provide a complete repair, this single-side service package bundles the primary wheel bearing with a premium multi-lip outer oil seal and a heavy-duty press-fit axle retaining ring.
