Frequently Asked Questions
Q: What axle does part number YHC50007 fit?
A: The YHC50007 is designed for the Dana Spicer 44 with 19 spline outer axle stubs. Verify your axle spline count before ordering.
Q: Why upgrade to the YHC50007 Hardcore Drive Flange?
A: Factory drive flanges can loosen under extreme off-road stress, causing axle walk-out and potential axle disengagement. The YHC50007 billet steel flanges lock the axle in place for reliable performance in rock crawling and high-torque situations.
Q: Do the YHC50007 flanges work with lockers?
A: Yes. The YHC50007 is fully compatible with factory and aftermarket locking differentials installed in the Dana Spicer 44. The heavy-duty flanges are specifically designed for the higher-torque conditions that lockers create.
Q: What is the warranty on YHC50007?
A: Yukon Gear covers the YHC50007 with a one-year warranty against manufacturer defects. Under the Magnuson-Moss Warranty Act, using aftermarket parts such as the YHC50007 does not void your vehicle's factory warranty unless the manufacturer can prove the part caused a specific failure.
Q: What tools are required to install YHC50007?
A: Basic hand tools, a torque wrench, and axle seal tools are typically required. Refer to the Yukon installation guide included with YHC50007 for specific requirements and torque specifications.
Q: Are the Yukon engraved caps included with YHC50007 functional?
A: Yes. The engraved caps provide the proper retention and protection for the drive flange hubs while also serving as a distinctive identifier of the Yukon Hardcore kit.
Q: Can I reuse my factory hardware with YHC50007?
A: We recommend using the hardware included with the YHC50007 kit. Reusing stretched or fatigued factory hardware may compromise the flange's retention under load.
Q: Is professional installation required for YHC50007?
A: The YHC50007 can be installed by experienced DIY mechanics. Proper torque on all fasteners is essential. If you are not confident in your axle work, professional installation is recommended.
