Why Opt for Locking Hubs? Many four-wheel drive vehicles are equipped with manual locking hubs, which, over time, may wear out and require replacement. Alternatively, some vehicles feature automatic locking hubs. While these provide convenience, they do not permit a full disengagement from the four-wheel drive system. Consequently, components such as axles, differentials, and driveshafts continue to operate even when the vehicle is in two-wheel drive mode, leading to increased wear and reduced fuel efficiency. By upgrading to a manual WARN 4WD Hub, drivers gain the capability to fully disconnect the front wheels from the drivetrain. This adjustment not only enhances fuel efficiency but also minimizes wear on the drivetrain components. At Texas Truckworks, we specialize in WARN locking hubs, offering our expertise throughout The Woodlands, Texas, and surrounding areas.
