Rear Axle Bearing & Seal Kit

2003-2006 Jeep Wrangler TJ | Dana 44 Rear Axle with Disc Brakes

Product Overview

Give your Jeep's rear axle the attention it deserves with this PORC Rear Axle Bearing & Seal Kit. Designed for 2003-2006 Jeep Wrangler TJ models equipped with a Dana 44 rear axle and factory rear disc brakes, this kit brings together the essential bearing, sealing, and retaining components for servicing one rear axle shaft assembly.

The rear axle bearing supports axle shaft rotation, while the axle shaft seal helps retain differential lubricant and limit contamination. The included retainer plate and collar are part of the axle shaft's bearing retention arrangement.

Whether you're addressing a worn axle bearing, replacing a leaking seal, or completing a targeted rear axle repair, this four-component kit provides the listed replacement parts together without requiring the purchase of a complete two-sided bearing and seal kit.

Understanding the Components

Rear Axle Bearing: The bearing supports the axle shaft as it rotates. Bearing wear or damage may result in abnormal axle noise, rough operation, or excessive movement. Proper inspection is necessary to determine the cause of these symptoms.

Outer Axle Shaft Seal: The seal helps prevent differential lubricant from escaping past the axle shaft sealing area. A damaged or worn seal may contribute to lubricant leakage near the axle end.

Retainer Plate: The plate forms part of the axle bearing retention and mounting arrangement. Correct fitment is important because axle retaining hardware differs between applications.

Retainer Collar: The collar is used in the bearing retention arrangement on the axle shaft. Installation requires the appropriate service procedure and equipment for the axle assembly.

When to Inspect Your Rear Axle

Rear axle bearings and seals are service components that may require replacement as wear or damage occurs. Common reasons for inspection include:

• Unusual humming, grinding, or rumbling noises from the rear axle area
• Visible differential lubricant leakage near the axle shaft or rear brake assembly
• Excessive axle shaft movement identified during inspection
• Damaged or worn components found during rear axle maintenance

These symptoms do not automatically confirm a failed axle bearing or seal. Other differential, brake, or axle components may produce similar symptoms and should be inspected before replacement parts are selected.

OE / Interchange Numbers

The numbers above are component and service references associated with the listed axle application. They do not indicate that every number identifies the complete four-component kit. Verify individual component compatibility before ordering.

Installation & Service Notes

Rear axle bearing replacement requires removal and servicing of the axle shaft assembly. Bearing and retaining collar removal or installation may require specialized press equipment and appropriate supporting fixtures.

Inspect the axle shaft bearing surfaces, seal contact areas, and associated retaining components before reassembly. Follow the correct factory service procedures for your Dana 44 axle, including applicable installation methods and specifications.

This package contains the four listed bearing, sealing, and retaining components. Additional service materials, lubricants, and tools are not specified as included.

Please confirm Jeep model, model year, Dana 44 rear axle configuration, factory rear disc brakes, and component reference numbers before purchase.
