Parts for Standard Duty Closed Knuckle Dana-Spicer 44 Front Axles in 1959-1975 Ford 4x4 Trucks

We stock a good selection of parts for 1959 to 1975 Ford 4x4s with standard-duty Dana 44 closed knuckle front axles. For the 1959 model year, Ford introduced the first factory built Ford 4x4 pickup which was available in both F-100 1/2 ton and F-250 3/4 ton drivetrains. The new, affordable, factory 4x4s replaced the previous Marmon-Herrington conversions of 4x2 to 4x4 trucks and allowed Ford to better compete with Dodge, GM, IHC, Jeep, and Studebaker all of whom had previously introduced factory built 4x4 pickups. The standard-duty Dana-Spicer Model 44 axle, which has 8 Bolt Knuckle Ball Seals, was used for all F-100 4x4s from 1959 to 1966, and for light duty F-250 3/4 ton trucks from 1959 through 1975. In 1961, an optional, Heavy-Duty version of the Dana-Spicer 44 front axles with 12 bolt Ball Seals was offered for the F-250.

Ford F-100 Closed Knuckle axles were replaced by a King Pin type open knuckle Dana 44 front axle during the 1967 model year. Ford continued to use standard duty Model 44 closed knuckle axles right through the 1975 model year on light duty F-250 4x4 trucks. Ford was the last U.S. vehicle manufacturer to use closed knuckle axles on 3/4 ton models. For 1976, all Ford F-250 4x4 trucks would have either an open knuckle Dana 44 (Regular Cab) or Dana 60 (Crew Cab).

Closed Knuckle Parts
We stock the regular service closed knuckle parts for your 1959-1975 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.

Differential and Pinion Bearings (Individual)
There was a differential Side Bearing change which according to Dana was effective with the 1967 model year. My Ford parts books do not give a year break and my memory is a bit hazy on which years took the small ID or Large ID Bearings, but I believe 1967 was the change over year.
All bearings are not created equal for fit or durability, so we only stock first class, long lasting, Timken® Differential and Pinion Bearings for your Dana front axle. Timken® was and is a a major original equipment supplier of top-notch bearing components to Dana Spicer. Since I first started rebuilding Dana axles in the mid 1970's, I have found Timken® Bearings to be the most consistent in relation to the published dimensions of any bearing on the market which makes rebuilding an axle right the first time a WHOLE lot easier!
