So I modified the truck for behind the axle steering. This allowed me to remove the large front servo mount, and move the links behind the axle for more protection. I also got rid of the servo saver. Steering is much better no, alot smoother than with the round spring style servo saver. Plus I have a much better approach angle, as the servo mount actually stuck out past the front wheels!
Basically just flipped the hubs so that the steering arms faced the rear, and fabbed up a link to tie them together, and another link to go from one hub to the servo arm. Made a L bracket to hold the servo, and attached the servo with servo tape and a zip tie. The servo just misses the chassis at full suspension compression. The long link that connects the hubs had to be slightly ben to clear the lower links, and the pinion. I may mod the hubs slightly to raise the link up a mm or two. If I can do that it will fit perfectly. Right now it lightly rubs on the lower links when the truck is fully articulated.
I plan to do the same with the rear steering, but I will leave the link behind the axle, as it will be easier to do. I will not have to worry about pinion clearance that way, and I can mount the cross link on top of the hub's steering arms to get it well off the ground. I will use the futaba servo reverser to link the two servos and provide trim for the rear servo.
Everything is mocked up in the pics, and it works great, epa is set at 100% and the throw is perfect in both directions. I will get it running and then go back and tidy up all of the hand made parts, and most likely convert to hex hardware, as the philips stuff is not that great.
