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

Eliminate rear wheel play, correct drivetrain noise, and stop stubborn differential fluid leaks across your entire rear axle with this genuine Spicer Rear Axle Wheel Bearing, Retainer & Seal Master Kit. Specifically engineered as a high-durability, complete dual-side original equipment replacement package for 1999–2004 Jeep Grand Cherokee WJ models, this master bundle contains all the primary heavy-duty structural and sealing 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 architecture of the WJ Grand Cherokee, the outer wheel bearings bear the brunt of both rotational drivetrain force and the physical weight of the vehicle's rear chassis. Over years of highway commuting or trail riding, 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 escalates with vehicle speed. As the bearings degrade, they force the axle shafts to rotate out of true alignment, rapidly tearing through the outer oil seals. Compromised seals allow highly pressurized differential gear oil to weep out onto your rear 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 end 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 alongside two brand-new, high-tensile strength press-fit retainer rings (locking collars). Sourcing a genuine Spicer bundle ensures perfect metallurgical construction and factory tolerances, preventing loose components or premature wheel-end failure. To complete the job permanently, this dual-side service package matches the primary wheel bearings and locking collars with premium multi-lip outer oil seals.
