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

Eliminate hazardous rear axle end-play, quiet down invasive wheel-end howling, and protect your brakes from destructive gear oil leaks with this genuine Spicer Rear Wheel Axle Bearing and Seal Master Kit. Specifically engineered to service the unique aluminum-center Dana 44 (Dana 44-A) rear axle assembly found exclusively on 1999–2004 Jeep Grand Cherokee WJ models, this single-side overhaul package replaces worn, noisy, or leaking wheel-end components.

On the Grand Cherokee WJ platform, a single outer tapered roller bearing handles the entire rear vehicle weight distribution and intense side-loading forces encountered during cornering or off-road trail articulation. Over high mileage, or when running oversized mud-terrain tires, the bearing elements naturally suffer from load fatigue. A failing rear wheel bearing typically introduces itself through a persistent, low-pitched cyclical roaring or grinding noise from the rear corner that changes pitch with vehicle speed, or a visible puddle of differential fluid coating the inside of your rear brake assembly due to a compromised seal. If ignored, a blown axle seal will quickly ruin your brake linings and can lead to catastrophic axle shaft walk-out.

This original equipment manufacturer (OEM) master service package supplies everything needed to properly press-rebuild one rear axle shaft. Sourcing genuine Spicer components ensures identical steel hardness, factory-correct outer diameters, and high-integrity sealing lip durometers required to keep gear oil safely inside the housing and trail grit locked out.
