Yukon Jeep JK Rubicon Dana 44 Rear Axle Shaft Kit - 32-Spline, 1541H Alloy
YA D44JKRUB-L
The Yukon Jeep JK Rubicon Dana 44 Rear Axle Shaft Kit is a heavy-duty replacement and upgrade for 2007–2017 Jeep Wrangler JK Rubicon models equipped with the factory Dana 44 rear axle. Manufactured from heat-treated 1541H alloy steel, this 32-spline axle shaft is built to handle the added torque and drivetrain loads created by larger tires, locking differentials, and aggressive trail use. It's a practical upgrade for daily-driven Jeeps, weekend trail rigs, and rock crawlers that need dependable rear axle strength without stepping up to a premium chromoly shaft.
Each Yukon axle shaft features a 32.625" overall length and is available in left-hand or right-hand configurations to match the factory JK Rubicon rear axle. The kit includes the axle bearing, seal, retainer, and ABS tone ring, making it easier to replace a worn or damaged shaft without sourcing those components separately. With 5x5" and 5x5.5" wheel bolt pattern compatibility, this shaft provides a strong foundation for factory-style replacement and compatible wheel-end configurations. Verify the selected side and axle setup before ordering.
Includes:
- (1) Yukon 1541H Alloy Rear Axle Shaft - Selected Left or Right Side
- (1) Rear Axle Bearing
- (1) Rear Axle Seal
- (1) Axle Retainer
- (1) ABS Tone Ring
Important: Sold as one axle shaft kit for the selected side, not a pair. Choose Left Hand or Right Hand before ordering. Verify whether the supplied bearing, retainer, and ABS components are pre-installed or require assembly before installation.

FAQ
What is the advantage of a 1541H alloy rear axle shaft?
1541H alloy steel provides a good balance of strength, toughness, and value for heavy-duty axle applications. It's a practical upgrade for trail Jeeps running larger tires or seeing more off-road use without stepping up to a premium 4340 chromoly shaft.
Will this axle shaft fit my Jeep JK Rubicon?
This kit is designed for compatible 2007–2017 Jeep Wrangler JK Rubicon models equipped with a Dana 44 rear axle and 32-spline shafts. Verify your axle configuration and select the correct left- or right-hand variant before ordering.
Will this fit a Jeep JK Non-Rubicon Dana 44 rear axle?
No. Factory JK Non-Rubicon Dana 44 rear axles commonly use 30-spline shafts, while this kit is designed for the 32-spline Rubicon configuration. The axle shaft must match the installed differential and wheel-end assembly.
Are the left and right rear axle shafts interchangeable?
No. This product is offered in separate left-hand and right-hand configurations. Select YA D44JKRUB-L for the left side or YA D44JKRUB-R for the right side. Verify the required shaft before ordering.
Does this kit include both rear axle shafts?
No. This listing includes one axle shaft kit for the selected side. Two separate kits are required to replace both rear axle shafts.
Does the kit include a bearing, seal, and ABS tone ring?
Yes. Each kit includes an axle bearing, axle seal, retainer, and ABS tone ring along with the selected 1541H alloy axle shaft. Confirm whether the components arrive assembled or require pressing before installation.
Can I use this shaft with the factory Rubicon locker?
This shaft is designed for compatible JK Rubicon Dana 44 rear axle applications using 32-spline differential components. Verify that the factory or aftermarket differential uses the correct spline configuration before installation.
What should I inspect when replacing a rear axle shaft?
Inspect the axle bearing, seal surface, axle housing, retainer, ABS tone ring, and differential side gear splines. Confirm the new shaft is correctly installed and that the wheel-end assembly rotates without abnormal movement before returning the Jeep to service.
