Yukon Dana 44 / Model 20 Axle Bearing & Seal Kit - Jeep CJ, Wagoneer and Scout
AK SET10
The Yukon Dana 44 / AMC Model 20 Axle Bearing & Seal Kit provides the replacement bearing and seal needed to service one side of a compatible axle assembly. Whether you're rebuilding a Jeep CJ rear axle, fixing a leaking axle seal, or replacing a worn bearing on a classic 4x4, this kit helps restore proper axle shaft support and sealing. It's a practical choice for Jeep restorations, trail rigs, and custom off-road builds using compatible Dana 44 or AMC Model 20 axle configurations.
Axle bearings and seals take a beating from regular driving, larger tires, water crossings, and trail use. Replacing both components together helps prevent leaks and gives the axle shaft a dependable bearing surface to operate on. This Yukon kit includes one axle bearing and one seal, so you can service the affected side without purchasing a complete axle rebuild package. Before installation, inspect the axle shaft bearing journal, seal surface, housing, and retaining components to make sure everything is ready for the new parts.
Includes:
- (1) Rear Axle Bearing
- (1) Rear Axle Seal
Important: This kit services one axle side. Order quantity (2) to service both sides of a compatible rear axle. Verify axle identification, bearing dimensions, and retention configuration before ordering.

FAQ
What comes in the Yukon AK SET10 bearing kit?
This kit includes one axle bearing and one axle seal. It is designed to service one side of a compatible Dana 44 or AMC Model 20 axle assembly.
Will this kit fit my Jeep CJ rear axle?
It is listed for compatible Jeep CJ5, CJ7, and CJ8 rear axle applications using Dana 44 or AMC Model 20 configurations. Verify the installed axle and bearing dimensions before ordering because these vehicles were produced with different axle arrangements.
Will this kit fit every Dana 44 axle?
No. Dana 44 axles were produced in several configurations with different bearing dimensions and retention methods. Confirm the installed axle and bearing application before purchasing.
Does this kit include bearings and seals for both sides?
No. This kit includes one bearing and one seal for a single axle side. Order quantity (2) if you're servicing both sides of a compatible rear axle.
What are common signs of a worn rear axle bearing?
A worn axle bearing may cause humming or grinding noises, vibration, or unwanted axle shaft movement. Leaking gear oil around the axle end can also indicate a worn seal or excessive shaft movement. Inspect the complete axle assembly to identify the cause before replacing parts.
Should I replace the axle seal when replacing the bearing?
Yes. Replacing the seal during bearing service is good practice, especially if the original seal has been disturbed or shows signs of wear. This kit includes both components so they can be serviced together.
Can this bearing kit be used on a custom axle build?
Yes, provided the axle housing, shaft bearing journal, seal dimensions, and retention method match the components supplied in the kit. Custom axle builds should be measured and verified before ordering.
What should I inspect before installing a new axle bearing?
Inspect the axle shaft bearing journal, housing bore, seal contact area, and retaining hardware. Look for grooves, scoring, corrosion, or damage that could shorten bearing life or prevent the seal from working correctly.
Does this kit include axle shafts?
No. This listing includes the axle bearing and seal only. Axle shafts and additional installation hardware are sold separately unless otherwise specified.
