Yukon Hardcore Locking Hub Set for Dana Spicer 30 and Dana 44 Differentials, 30 Spline, Part YHC70005
The Yukon Gear YHC70005 Hardcore Locking Hub set brings all-steel, Chrome-Moly reinforced manual locking hub performance to Dana Spicer 30 and Dana 44 front differentials equipped with 30 spline axle shafts. Built for street, towing, and off-road use, the YHC70005 features a low-profile bezel that minimizes trail impact, a proprietary low-friction coating on the locking gears for long service life, and a default-locked engagement mode that prevents unintended disengagement under high-torque loads. Engagement and disengagement happen in one-third of a turn. A Limited Lifetime warranty against manufacturer defects is standard.

Frequently Asked Questions
What differentials does the YHC70005 fit?
The YHC70005 fits Dana Spicer 30 and Dana 44 front differentials with 30 spline front axle shafts. This covers many Jeep Wrangler TJ non-Rubicon and Dodge Ram 4WD applications.
How do I confirm the YHC70005 is the right hub for my vehicle?
Remove the existing hub or spindle cap and count the splines on the axle stub shaft. If the count is 30, the YHC70005 is correct. For 19-spline applications, see the YHC70006.
Does the YHC70005 work with Stage-8 lock nuts?
No. The YHC70005 is not compatible with Stage-8 lock nuts. Standard OEM-style spindle nuts are required.
Will installing the YHC70005 affect my powertrain warranty under the Magnuson-Moss Warranty Act?
The Magnuson-Moss Warranty Act prevents a manufacturer from voiding your warranty simply because an aftermarket part was installed. The warranty can only be denied if the manufacturer proves the YHC70005 directly caused the failure in question.
What warranty covers the YHC70005?
Yukon provides a Limited Lifetime warranty against manufacturing defects on the YHC70005 locking hub set.
How quickly does the YHC70005 engage?
One-third of a turn of the all-steel low-profile bezel moves the hub from fully free to fully locked. No additional tools are required.
Are there universal-fit locking hubs, or is the YHC70005 application-specific?
The YHC70005 is designed specifically for Dana 30 and Dana 44 hubs with 30-spline axle shafts. Always verify your spline count and differential type before ordering.
Can the YHC70005 be installed at home?
Yes. Installation requires only standard hand tools. No press or specialty equipment is needed for the hub assembly itself. Basic mechanical experience with front axle components is recommended.
Installation Instructions
- Raise and support the front of the vehicle safely on jack stands and remove both front wheels.
- Remove the existing locking or free-wheeling hubs by extracting the face mounting screws.
- Clean the spindle threads and stub shaft splines, removing any old grease or debris.
- Confirm 30-spline count on the stub shaft before installing YHC70005 components.
- Thread and torque the spindle nut per your vehicle service manual specification.
- Install the inner body of the YHC70005 onto the stub shaft splines and seat fully.
- Secure the inner body with the included retaining snap ring or clip.
- Place the outer bezel assembly over the inner body and align the mounting holes.
- Install and torque the face retaining screws per specification.
- Repeat on the opposite wheel. Reinstall wheels and road-test in both 2WD and 4WD modes to confirm proper engagement and disengagement.
