Yukon Jeep JK Dana 44 Rear Bearing & Seal Kit
AK D44JK
The Yukon Jeep JK Dana 44 Rear Axle Bearing & Seal Kit provides the replacement bearing and seal needed to service one side of a compatible 2007–2018 Jeep Wrangler JK rear axle. Whether you're fixing a leaking axle seal, replacing a worn bearing, or refreshing your rear axle during a larger Jeep build, this kit helps restore proper axle shaft support and sealing. It's a practical replacement for daily-driven Jeeps, trail rigs, and off-road builds running larger tires and putting more load on their factory axle components.
The Dana 44 rear axle is a solid foundation for a Jeep JK build, but larger tires, added vehicle weight, and regular trail use can take a toll on axle bearings and seals. Worn components can lead to gear oil leaks, bearing noise, and unwanted axle shaft movement. This Yukon kit includes one replacement bearing and matching seal so both components can be serviced together. Before installation, inspect the axle shaft bearing surface, seal contact area, and retaining hardware to make sure the new parts have a solid foundation.
Includes:
- (1) Jeep JK Dana 44 Rear Axle Bearing
- (1) Matching Rear Axle Seal
Important: This kit services one rear axle side. Order quantity (2) to service both sides of a compatible rear axle. Verify the installed axle configuration before ordering.

Builder Note: Jeep JK rear axles may have been upgraded with aftermarket shafts, lockers, or complete axle assemblies.

FAQ
What comes in the Yukon AK D44JK bearing kit?
This kit includes one rear axle bearing and one matching axle seal. It provides the components needed to service one side of a compatible Jeep JK Dana 44 rear axle.
Will this kit fit both Rubicon and non-Rubicon Jeep JK models?
Yes, this kit is listed for compatible Rubicon and non-Rubicon Jeep JK models equipped with Dana 44 rear axles. Verify the installed axle and bearing configuration before ordering, especially if the Jeep has aftermarket axle shafts or a modified housing.
Will this fit a 2018 Jeep Wrangler?
This kit is listed for 2018 Jeep Wrangler JK applications equipped with the compatible Dana 44 rear axle. It should not be assumed to fit the newer JL Wrangler, which uses different axle configurations.
Does this kit include bearings and seals for both sides?
No. One kit includes one axle bearing and one seal for a single rear axle side. Order quantity (2) to service both sides of a compatible Dana 44 rear axle.
What are common signs of a worn Jeep JK rear axle bearing?
Common symptoms include humming or grinding noises, vibration, unwanted axle shaft movement, and gear oil leaking near the rear brakes or axle ends. 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 axle bearing service is good practice, especially when the original seal has been disturbed or shows signs of wear. This kit includes both components so they can be serviced together.
Can I install this kit when upgrading rear axle shafts?
Yes, provided the replacement axle shafts use the same compatible bearing and seal configuration. If you're upgrading to aftermarket chromoly shafts or rebuilding the axle, replacing worn bearings and seals during assembly can help reduce future maintenance.
Does this kit include differential carrier or pinion bearings?
No. This is a rear axle shaft bearing and seal kit. It does not include differential carrier bearings, pinion bearings, or ring and pinion setup components.
What should I inspect before installing new rear axle bearings?
Inspect the axle shaft bearing journal, housing bore, seal contact surface, and retaining hardware. Look for scoring, grooves, corrosion, or other damage that could shorten bearing life or prevent proper sealing. Follow the axle manufacturer's installation procedure for proper assembly.
