Printed the 3rd axle and it's in place(need to take pics), 2nd axle is still being modeled. Didn't have the time to sit and finish it properly.

But I've made this:










My steering was like this before:



It was to try to make it more scale and also hide the servo. Well, it kind of worked. Even with a 25kg servo, it seemed to lack torque and in bad spots, the servo just won't turn the wheels. Besides, tie-rods hit each other.
So, simple is better and now the servo is mounted on the bumper. Made 2 brass mounts and the servo is angled to clear the bottom of the cab and also the servo horn(+rod-end) clear the steering rod
