Had to be a Schwarzenegger to steer that thing. Look at the size of that steering wheel, and check out the tow-in on the sideways picture!
 
I asked about the Mack, he says yeah, no u joints or knuckles on the steering axle. It uses gears on the top and bottom of the king pins to drive the wheel somehow. I'll see if I can find a pic
 
It might be one of the early constant velocity types. Marmon Herrington developed stuff like that back in the 30s. A lot of stuff was shared during the war. Patents were overlooked for military equipment during that period since no civilian vehicles were being manufactured.
 
No cv joints in Mack NOs. All gears. Marmon Herrington used an existing cv joint called a Bendix (not MH’s design at all), same as some WW2 jeeps. Not the strongest joint, a Rzeppa was much better, a uJoint better still. Early Jeeps had all 3 variants. Weiss patented the Bendix joint in 1920, Rzeppa filed patent in 1927

I can’t make a link work, but Armorama site has a kersploded view of this Mack axle. Enough gears to compete with that above pictured tandem drive Ford. Google Mack NO 6x6 front axle.

Here's the Mack axle, I wonder if my Kubota tractor is similar as the housing shape looks the same

Wow! That is really something. So what we are seeing here are kingpins spinning in roller bearings doing double duty in the power delivery as well? This has been a very interesting thread.
