Shop now for Closed Knuckle Parts to fit 1959-1966 Ford F-100 and F-250 8 Bolt Dana 44 Front Axles. Great selection. In stock. Quick shipping.
We stock the regular service closed knuckle parts for your 1959-1965 Ford F100 or light duty F-250 4x4 with a standard closed knuckle Dana 44 front axle which will have 8 bolt Knuckle Ball Hemisphere Seals. With a Closed Knuckle axle, the axle universal joints and king pin bearings are lubricated by very heavy oil or a viscous grease that will flow when the axle shafts rotate. A large, multi-piece seal is bolted to the backside of the steering knuckle to keep lubricant in and water out. On poorly maintained closed knuckle axles or axles equipped with lockout hubs that are rarely used in 4x4, the upper king pin bearing and axle universal joint can suffer from lack of lubrication. The Ball Seals will usually weep some lubricant especially when standard gear oils are used as a lubricant. Submersion of the axle under water or condensation from temperature changes can cause moisture to build up inside the enclosed ball and lead to corrosion damage and part failures.
