I put standard sprung shocks on the rear axle to see how it feels. Definitely works better, the axle freely moves now, but it does sag a little. Depending on what the truck ends up weighing the sag may become an issue, but it will also have another 2 axles to spread the load on, so who knows, might be ok.
Might even be able to find some stiffer springs to put in the shock.

Have also discovered that the small steering arms that mount to the C hub interfere with the tire and wheel. Will have to make some new ones for front and rear.

And the rear tires hit the screw holding the lower link when turned as well. May not be an issue though since the rear wheels steer less than the front.
