Tech Note 1: U-Joint Specs
TK42303 Axle Shaft takes universal joints made to Spicer 1350WJ dimensional specifications. The cup diameter for these u-joints is 1-3/16". The 4 cups are grooved to accept Inside C-Clip Snap Rings. The installed Clips fit against the machined inner faces of the axle shaft yokes. The distance between the inside of the axle shaft yoke ears is 2-3/16". For matching u-joints, see TK40712 and QU90007.

Tech Note 2: Axle Types
Up through the 1975 model year, the 4x4 Ford F250 used closed knuckle, drum brake equipped front axles. Totally new, open knuckle, disc brake equipped axles were introduced for the 1976 model year. Very few hub, axle shaft, or steering parts are interchangeable between the two axle types.

Tech Note 3: 1977 Change
The Ford F250 underwent a major, mid-year model change in 1977 effective with serial number Y20001. Regular Cab F250 4x4s built before serial number Y20001 are "high boy" models with remote mount transfer cases and Dana 44 front axles with bolt-on type hub locks or drive flanges. 1977 regular cab 4x4s built after serial number Y20000 are "low boy" models with direct mount transfer cases and Dana 44 front axles with internal spline mount hub locks or drive gears.

Tech Note 4: Axles
The standard front axle on 1978-1979 Ford F-250 3/4 ton 4x4 trucks is a 3800 pound rated Dana 44 solid beam type front axle with internally splined wheel hubs. The end of the wheel hub measures about 3-5/8" in diameter and the spindle thread is 1-5/8". A 4500 pound rated Dana 60 was optional on 1978-1979 F-250 models. The optional Dana 60 will have a front wheel hub that measures about 4-1/8" at the outer end and a 2" spindle thread.

Tech Note 5: Axle U-Joints
Inner axle shaft operating failures are usually a result of a broken axle u-joint. Good preventative maintenance can usually prevent those type of failures. A good number of axle shafts are also wrecked by poor service procedures during u-joint replacement. Over the years I have seen a lot of axle shafts with bent or broken yokes caused by the slam-bang u-joint removal and installation methods. A QT1065M C-Frame Press with the correct adapters is both the safest and best way to remove or install axle u-joints.

Tech Note 6: Axle Seals
Axle shaft seal leaks on older vehicles can occur any time an axle shaft is removed and replaced/reinstalled. The most common causes are the inner axle shaft seal lip has become worn and brittle with age and/or crud in the axle tube was pushed into the seal when the axle shaft was installed. The best thing to do is to replace the inner axle shaft seals before reassembling your axle, but you MUST remove the differential to replace the seals. With either new or old seals, always make sure the splines and seal surface on your inner axle shaft is clean and dry before installing the axle shaft.
