Spicer Rear Wheel Axle Bearing & Seal Kit with Disc Brakes for 1997-2006 Jeep Wrangler TJ & LJ (Dana 44, Single Side)

Eliminate hazardous rear axle end-play, stop invasive wheel-end howling, and safeguard your vehicle from destructive gear oil leaks with this genuine Spicer Rear Wheel Axle Bearing and Seal Kit. Specifically engineered to service classic 1997–2006 Jeep Wrangler TJ and Unlimited LJ models configured with a heavy-duty Dana 44 rear axle and factory disc brakes, this single-side overhaul package replaces worn, noisy, or leaking wheel-end components.

On semi-floating rear axle architectures, a single outer bearing handles the entire vehicle weight distribution and intense side-loading forces encountered while cornering or navigating off-road terrain. Over high mileage, or when running oversized mud tires, the bearing elements naturally suffer from 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 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.
