Frequently Asked Questions

What axle does YHC70001 fit?
YHC70001 is designed for Dana 60 front axles with 35-spline stub shafts. It fits 1979-1991 GM K30/K3500/V30/V3500, 1978-1997 Ford F-250/F-350, and 1979-1993 Dodge W200/W250/W300/W350 trucks with the Dana 60 front axle.

What does "defaults to locked" mean?
The Hardcore hub defaults to the locked position, meaning the hub mechanically engages the axle shaft even if the locking collar is not manually turned. This is a safety advantage over hubs that default to free-wheeling, ensuring you maintain 4WD engagement on the trail even if the hub is not actuated.

How does the engagement work on YHC70001?
The hub engages or disengages with approximately a one-third turn of the locking cap. This is a quick, positive action that can be performed without tools.

Are the internals stronger than factory hubs?
Yes. YHC70001 uses chromoly steel internal components, which are significantly stronger than the pot metal or aluminum internals commonly found in OEM-style replacement hubs. The all-steel construction means there is no risk of heat-related deformation.

Will this void my vehicle's warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your vehicle warranty solely because you installed an aftermarket part like YHC70001 unless they can demonstrate the aftermarket part caused the specific failure being claimed. Consult your dealer if you have warranty concerns.

Is YHC70001 compatible with Stage-8 lock nuts?
Yes, YHC70001 is compatible with standard applications. If you are running Stage-8 lock nuts, verify fitment with your specific hub bolt pattern before ordering.

Does this hub work with auto-locking hubs?
No. YHC70001 is a manual locking hub set and replaces any automatic or vacuum-actuated locking hubs with a manual mechanism. You must physically turn the hub cap to lock and unlock.

What is the warranty on YHC70001?
Yukon Gear covers YHC70001 with a limited lifetime warranty against defects in materials and workmanship. This warranty covers the original purchaser.

Installation Instructions

1. Safely lift the front of the vehicle and support it on jack stands. Remove the front wheels.
2. Remove the existing locking hub or free-wheeling hub assembly by removing the retaining bolts from the hub cap and pulling the hub body outward.
3. Clean the stub shaft splines and the hub mounting face thoroughly. Remove any old gasket material.
4. Slide the new YHC70001 hub body onto the stub shaft splines, aligning the mounting bolt holes with the rotor hat.
5. Install and torque the mounting bolts to specification (typically 35-40 ft-lbs; refer to the included instructions for vehicle-specific torque values).
6. Install the locking collar onto the hub body, verifying it engages and disengages smoothly with a one-third turn.
7. Reinstall the front wheels and torque lug nuts to specification.
8. Lower the vehicle. Engage 4WD and test both hubs for positive engagement and disengagement before driving.
