Applications

Tech Note 1: Axle Shaft Note
Most of the outer axle shafts we sell are for Dana 70 axles in pulling trucks. While the old Dana 70s are good, stout axles, they are marginal for use in 1000 hp competition rigs (As are any axles from less than a 10-ton truck!). Since the outer shaft is only 1-3/8" in diameter they will twist off under severe loads. Our Torque King® Heavy-Duty Chrome-Moly shafts are much stronger than QU40452 factory shafts, but they are not bullet proof. We will not warranty shafts wrecked from abuse, misuse or competition.

Tech Note 2: No Snap Ring Groove
Just like the stock shafts, TK40689 Axle Shafts do not have a snap ring groove cut in the splines. Axle Shaft Thrust is controlled by QU40431  Spindle Bushing (for Stock Shafts) and TK42172 Spindle Bushing (for Torque King shafts) pressed in the spindles and axle tubes.

Tech Note 3: U-Joints
Dana has discontinued the hot-forged, seal-less, solid cross axle shaft u-joints for this application. All our current u-joints have seals which I recommend you remove so lubricant from the knuckle can flow to the needle rollers. TK40715 is a cold-forged, premium strength, solid cross axle u-joint. QU30332 is a hot-forged, cross-drilled u-joint which will physically fit the axle shafts, but since it is cross-drilled, there will be a little loss of strength compared to the original joint.

Tech Note 4: 1958-1974 Dodge with Tracta Joints
To fit through the spindle hole in the knuckle, 1958-1974 Dodge W300 4x4s were factory equipped with relatively weak Tracta type axle shaft assemblies which are out of production. You can replace the Tracta type axle shaft assemblies with our stronger Chromoly Spicer type 1480WJ Axle Shafts similar in design to the factory shafts used in 1961-1975 IHC Dana 70 Axles and 1967-1969 Jeep M715 Front Axles. The yoke diameter of these shafts is too large to fit through the spindle hole in your knuckle, so to install/remove our axle shaft assemblies, you HAVE to remove the steering knuckle!

Tech Note 5: Dodge-Must Replace Assembly
If you are replacing Tracta Type Axle shafts in 1958-1974 Dodge W300 4x4s, You have to replace the entire shaft which means you are replacing the Inner Shaft, Outer Shaft, and Axle U-Joint.
