National 340151 steering gear pitman shaft seal, steering gear sector shaft seal for the 1975-1982 Ford F-150 and other vehicles seals the opening where the pitman shaft leaves the steering gear housing. The pitman shaft is also called the sector shaft.
Fluid weeping from the steering gear, or a wet, dirty housing around the shaft, can mean the seal is worn. Before you replace it, rule out other sources of the leak, such as a nearby hose or fitting, because fluid from elsewhere can run down onto the housing. The steering gear takes one seal.
Vehicles it fits include the 1965-1982 Ford F-250 and the 1964-1968 Ford Mustang, alongside the 1975-1982 Ford F-150. If your car isn't named here, look up its year, make and model in the Buyer's Guide tab.
