Frequently Asked Questions

What does the Yukon YHC50001 replace?
The YHC50001 replaces the internal manual locking hub assembly on Dana 44 front axles. Instead of a lockable hub, you get a solid drive flange that keeps the front axle shafts engaged full time.

Is this a full-time engagement setup?
Yes. Removing the manual locking hubs and installing solid drive flanges means the front axle shafts rotate with the wheels at all times. Engage or disengage the 4WD system using your vehicle's transfer case, as the hubs no longer control engagement.

How many splines does this kit require?
The YHC50001 is designed for Dana 44 axles with 30-spline outer stub shafts. Confirm your axle spline count before purchase.

Is this kit compatible with Dana 60 axles?
No. The YHC50001 is specific to Dana 44 front axles. For Dana 60 applications, see the Yukon YHC70003.

Does this kit include everything needed for installation?
Yes. The YHC50001 includes two drive flanges, two Yukon-engraved caps, and all necessary hardware for a complete installation.

What vehicles use a Dana 44 front axle with 30-spline outer stubs?
A wide range of classic and vintage 4WD trucks and SUVs used the Dana 44 front axle, including many Jeep CJ and Wagoneer models, Ford Broncos and F-Series trucks from the 1960s through 1970s, and full-size Chevrolet/GMC K-series trucks. Always verify your specific axle configuration before ordering.

What is Yukon Gear and Axle's warranty on this product?
Yukon Gear and Axle backs the YHC50001 with a Lifetime Warranty, supported by the Magnuson-Moss Warranty Act. Coverage applies to manufacturing defects. Commercial, racing, and competition use may have separate terms.

Can these flanges be used with aftermarket axle shafts?
Yes, as long as the aftermarket shafts feature 30-spline Dana 44 outer stub geometry that matches the factory specification. Consult Yukon or your axle shaft manufacturer to confirm compatibility.
