A broken shift dial, a cracked or dry-rotted diaphragm, or 4WD that will not engage or release can be signs of a failing hub. A worn wheel bearing, a worn axle shaft or a fault elsewhere in the 4WD system can be behind these signs too, so find the cause before buying.
Fits
It also fits the 2000-2005 Ford Excursion, and the same locking hub fits the 1999-2004 Ford F-250 Super Duty. A vehicle takes two hubs, one for each side of the axle. This listing is one hub, and both sides are normally replaced together. Owners of other Ford and Lincoln models can look up their own year and model in the "Vehicles it fits" section.
