listen carefully..."independent front suspension....I'm pretty sure that bright yellow thing is a solid axle.

Look closer, its a traction beam, bit of a cross between modern ifs and a solid axle.

explains why only ford used them. so basically the long axle side can move up and down some what. Just watching that video a few times over it doesn't seem to give a huge amount of independent movement. but in saying that the surface although rough it is driving over isn't exactly making that aspect of the axle articulate that much.

Both sides are "hinged" on the opposite chassis rail or there abouts, the drive comes into the diff head, which is in one side the there is a cv and axle shaft driving out to the other wheel.

Lack of flex in the vid is in part to the leaf springs.

There is the odd set up around in the us race scene but mainly older stuff from what I have seen. Have the down side of camber change as the knuckle is attached to the end like a single a-arm, so you can't design in the camber change you want through the arc of travel.

Cant find it but have seen footage of a desert truck jumping and it looks all wring as the wheel droop and go into massive camber.

Same system used on the ex Warren Arthur Camco Ford F150 in off road racing. Photos of it in NZ4WD magazine last year from Taupo 1000 including one of it suspended mid air and another full compressed on landing.
It is commonly called a Twin Traction Beam or TTB.
