Rear Axle Bearing & Seal Kit Pair
2003-2006 Jeep Wrangler TJ | Dana 44 Rear Axle with Disc Brakes
Product Overview
Refresh both sides of your Jeep's rear axle with this PORC Rear Axle Bearing & Seal Kit Pair. Designed for 2003-2006 Jeep Wrangler TJ models equipped with a Dana 44 rear axle and factory rear disc brakes, this kit combines the bearing, sealing, and retaining components listed for servicing both rear axle shafts.
Rear axle bearings support axle shaft rotation, while axle shaft seals help retain differential lubricant and limit contamination. The associated retaining components are part of the axle shaft bearing mounting and retention assembly.
Unlike a single-side replacement kit, this both-side service package provides matching component sets for the left and right rear axle shafts. It is intended for owners performing a complete rear axle bearing and seal service or addressing wear on both sides of the axle.

One bearing for each rear axle shaft, providing support during axle shaft rotation.

One seal per side to help maintain the lubricant barrier at the rear axle shaft sealing locations.
2 x Axle Bearing Retainer Collars
Retaining collars associated with securing the bearings on their respective axle shafts.
2 x Axle Bearing Retainer Plates
Retaining plates used in the rear axle bearing mounting arrangement.
2 x Press Rings
Listed press-ring components associated with the rear axle bearing service assembly.

Understanding the Components
Rear Axle Bearings: Support the rear axle shafts and allow rotation within the axle assembly. Bearing wear or damage can contribute to abnormal noise, rough operation, or excessive axle shaft movement.
Outer Axle Shaft Seals: Help prevent differential lubricant from escaping at the axle shaft sealing locations. Proper sealing also helps limit the entry of contaminants into the assembly.
Retainer Collars: Components used in the bearing retention arrangement on the axle shafts. Correct installation is essential to the assembly.
Retainer Plates: Form part of the bearing and axle shaft mounting arrangement. Their design must match the applicable rear axle configuration.
Press Rings: Listed components associated with the axle bearing service assembly. Follow the applicable axle service documentation to identify their correct installation positions.
Why Service Both Sides?
When performing a comprehensive rear axle service, replacing worn or damaged bearing and sealing components on both sides may be appropriate depending on their condition.
This kit makes it possible to obtain the listed left- and right-side components together, rather than purchasing two separate single-side kits.
A complete inspection should determine whether bearing, seal, or additional axle components require replacement. This kit does not replace the need to inspect the axle shafts, differential, or brake components.

Installation & Service Notes
Rear axle bearing and seal replacement requires removal and servicing of the applicable axle shaft assemblies. Specialized bearing removal and installation equipment may be required.
Inspect the axle shaft bearing surfaces, sealing areas, retaining components, and related hardware during disassembly. Follow the appropriate factory service procedures for your Dana 44 axle, including specified installation methods and reassembly requirements.
The package contains the listed bearing, sealing, and retaining components for both sides. Additional service tools, lubricants, and unrelated axle components are not specified as included.
