Surwit 1C3Z3B396CB 1999 2004 2000 2005 Expedition Review

The 4X4 4WD Auto Locking Hub is located on the front wheel hubs the 4WD actuators control power transferred from the axle assembly to the front wheels. The hub then remains in the locked position as long as the transfer case remains in four-wheel drive. When the driver shifts to two-wheel drive, the clutch mechanism inside the hub slides back out and releases the hub, allowing the wheel to turn independent of its axle shaft. This auto locking hub fits both front left or front right wheel locking hubs on 1999 - 2004 Ford F250, F350, F450, F550 Super Duty, 2000 - 2005 Ford Excursion, 2001 - 2002 Ford Expedition and Lincoln Navigator. Customers can find the product you need accurately according to the OE number. OEM replace part number: 1C3Z-3B396-CB, 1C3Z3B396CB, 600-203. This auto locking hub fits 99 00 01 02 03 04 05 years Ford cars. The main advantage of being able to disengage the front wheels on the go is that the driver doesn’t have to stop, get out of his vehicle and twist a dial on the hub to disengage or engage the front wheels. The automatic locking hub does it automatically on the fly. Fuel economy may improve as much as one mile per gallon, depending on the vehicle, by disconnecting the front wheels. The most common problem with automatic locking hubs is the hub won’t engage. Mud, rust or worn parts inside the hub can prevent the mechanism from sliding in and locking the hub. For the same reasons that prevent the hub from engaging, a hub may also fail to release. Anything that binds the internal mechanism can prevent it from sliding and releasing. The most noticeable symptoms may be an increase in fuel consumption, noise on the highway and/or increased front-tire wear.
