YHC70004 replaces factory hubs with an all-steel, chromoly-internals design that defaults to the locked position, keeping you in 4WD engagement when you need it on the trail or job site. With a low-profile bezel and one-third turn operation, this hub set gives Super Duty owners a heavy-duty, reliable alternative to OEM-style units that can wear out under sustained off-road

Questions\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eWhich Ford Super Duty years does YHC70004 fit?\u003c\/strong\u003e\u003cbr\u003e\nYHC70004 fits 1999-2004 Ford F-250 and F-350 Super Duty trucks equipped with the Dana 60 front axle and 30-spline stub shafts. Verify your axle spline count before ordering if you have had any prior axle work done.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan YHC70004 be used with Stage-8 lock nuts?\u003c\/strong\u003e\u003cbr\u003e\nNo. YHC70004 is not compatible with Stage-8 lock nuts. If your vehicle is running Stage-8 lock nuts, this hub set will not fit correctly. Please verify your hardware configuration before purchasing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between YHC70001 and YHC70004?\u003c\/strong\u003e\u003cbr\u003e\nYHC70001 is the 35-spline version for 1979-1997 GM, Ford, and Dodge applications. YHC70004 is the 30-spline version designed specifically for 1999-2004 Ford Super Duty trucks. Both use the same all-steel, chromoly-internal design, but they are not interchangeable due to spline count differences.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does it mean that the hub \"defaults to locked\"?\u003c\/strong\u003e\u003cbr\u003e\nA hub that defaults to locked is mechanically engaged with the axle shaft at rest. Even if the locking cap is not turned to the locked position manually, the hub maintains a connection with the shaft. This prevents you from accidentally driving in free-wheel mode when you need 4WD.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill installing YHC70004 void my factory warranty?\u003c\/strong\u003e\u003cbr\u003e\nUnder the Magnuson-Moss Warranty Act, a manufacturer cannot void your warranty solely due to the installation of an aftermarket part like YHC70004, unless they can prove the part caused a specific failure. Consult your dealership with any specific warranty questions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow difficult is installation?\u003c\/strong\u003e\u003cbr\u003e\nHub replacement is a moderate DIY job. It requires removing the wheel, unbolting the existing hub assembly from the rotor hat, sliding the new hub onto the stub shaft splines, and torquing to spec. A basic socket set and torque wrench are sufficient for most applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs a gasket included?\u003c\/strong\u003e\u003cbr\u003e\nMounting hardware is included.

Clean the splines and hub mounting face, removing any old sealant or gasket material.\u003c\/li\u003e\n\u003cli\u003eConfirm your stub shaft is 30-spline before proceeding.
