When 4WD is selected, the hub's internal clutch mechanism slides and locks; when returned to 2WD the clutch releases so the wheels turn independently, reducing driveline drag.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOperates automatically with transfer-case engagement — no manual hub switching required\u003c\/li\u003e\n  \u003cli\u003eInternal clutch\/actuator aligns to transfer torque when 4WD is in use\u003c\/li\u003e\n  \u003cli\u003eReduces front differential and engine load when in 2WD, improving efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the key features and how do I replace them?\u003c\/h3\u003e\n\u003cp\u003eThe kit replaces OEM part numbers listed above and installs using common tools without removing the wheel in most cases.

While exact fuel savings vary by vehicle and driving conditions, disengaging the front axle reduces unnecessary load during normal 2WD driving.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDisengages front wheels in 2WD to reduce driveline drag\u003c\/li\u003e\n  \u003cli\u003eHelps limit wear on front differential when not using 4WD\u003c\/li\u003e\n  \u003cli\u003eRestores proper automatic engagement so 4WD functions reliably when needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: This DICMIC 2-piece automatic locking hub kit is aimed at owners of compatible Ford Super Duty trucks and the listed SUVs who need a like-for-like replacement for worn, damaged or non-functioning factory hubs.
