Yukon Gear Rear 4340 Chrome-Moly Replacement Axle For Dana 60 w/ 30 Spline (Single Axle)

Yukon Gear 4340 Chrome Moly Replacement Axle for Dana 60 Rear 30-Spline Cut-to-Fit 34 to 36.5 Inch

The YA WFF30-36.5 from Yukon Gear and Axle is a premium 4340 chrome moly rear axle shaft engineered for the Dana 60 full-float rear differential with a 30-spline count and a cut-to-fit length range of 34 to 36.5 inches. The Dana 60 is the heavy-duty rear axle standard in full-size Ford F-250, F-350, Dodge Ram 2500 and 3500 trucks, and is also used in lifted Jeep builds and custom applications. The YA WFF30-36.5 replaces cracked, bent, or twisted factory axle shafts with a significantly stronger 4340 chrome moly unit that resists the extreme torsional loads generated by high-horsepower engines, aggressive off-road use, and heavy towing. Yukon precision-machines the spline and flange ends of the YA WFF30-36.5 to exacting tolerances, and the cut-to-fit design means you trim it to your exact housing dimension for a proper fit. This axle is covered by Yukon's limited lifetime warranty.

Frequently Asked Questions

• Q: What differential does the YA WFF30-36.5 fit?
  A: The YA WFF30-36.5 fits Dana 60 full-float rear differentials in Ford F-250 and F-350 Super Duty trucks from 1999 through 2015, Dodge Ram 2500 and 3500 trucks from 1994 through 2002, and other vehicles equipped with 30-spline Dana 60 full-float axle housings in the 34-to-36.5-inch range.
• Q: Why choose 4340 chrome moly over the factory axle shaft?
  A: Factory Dana 60 axles use 1040 steel. The YA WFF30-36.5 uses 4340 chrome moly alloy which delivers significantly higher tensile strength and torsional fatigue resistance, especially important in high-horsepower diesel trucks, extreme off-road applications, and heavily loaded towing vehicles.
• Q: How do I determine the correct cut length?
  A: Remove your existing axle shaft and measure from the end of the splines to the outer flange face. Cut the YA WFF30-36.5 to that measurement, confirming it falls within the 34-to-36.5-inch range.
• Q: Is this axle sold as a pair?
  A: No. The YA WFF30-36.5 is sold as a single axle shaft. Order two for a complete axle replacement.
• Q: Can installing aftermarket axle shafts affect my factory warranty?
  A: Under the Magnuson-Moss Warranty Act, a dealer must demonstrate that the YA WFF30-36.5 directly caused the failure before voiding your drivetrain warranty coverage.
• Q: What tools are required to cut this axle to length?
  A: A quality metal chop saw or cold saw is recommended. After cutting, deburr and lightly chamfer the cut end to prevent binding when inserting into the housing.
• Q: What warranty comes with the YA WFF30-36.5?
  A: Yukon backs the YA WFF30-36.5 with a limited lifetime warranty against manufacturing defects.
• Q: Is professional installation recommended?
  A: Full-float axle shaft installation is accessible for experienced mechanics, but cutting to length requires precise measurement and proper tools. Professional installation ensures correct fit and avoids costly errors.

Installation Instructions

8. Reinstall the wheel and torque lug nuts to specification.
9. Repeat on the opposite side if replacing both axle shafts.
10. Check differential fluid level and top off as needed.
