Parts for 1961-1975 International 4x4 Trucks with FA18 and FA25 Dana 44 Heavy Duty Front Axles

In the early 1960s, what most folks now call the Dana 44 Heavy-Duty Closed Knuckle Front Axle was referred to as a Spicer Model 44HD Front Drive Axle. International first used the Model 44HD FA18 closed knuckle front axle as an upgrade option for the 1961 C-120. Compared to a standard Model 44, the HD axle has a higher weight rating, larger axle u-joints, and larger knuckle bearings. The 44HD can be identified by 12 bolt Knuckle Ball Seal which is much larger than the 8 bolt seal used with the standard 44. FA18 and the similar FA25 3/4 ton axles were used in production IHC vehicles through the 1973 model year although Dana does list the FA18/FA25 for 1974 and 1975.

Closed Knuckle Parts

top_page
product note

We stock the regular service closed knuckle parts for your 1956-1975 IHC Regular 3/4 ton 4x4 with a closed knuckle Dana 44 Heavy Duty front axle which will have 12 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)

top_page
product note

There was a IHC Dana 44HD differential Side Bearing change which depending upon what parts book you believe was effective anywhere from 1967 to 1971. It is quite possible the change did not take place in a single year, but over several years as International used older axles they had on hand during vehicle assembly. One thing is for sure, you should verify what diff side bearing you have before ordering!
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!
