Shop now for Closed Knuckle Parts to fit 1946-1964 Jeep Utility Wagons and Utility Trucks equipped with the Dana-Spicer Model 25 Closed Knuckle Front Axles.
We stock the regular service closed knuckle parts for your 1946-1964 Jeep with a closed knuckle Dana 25 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.
