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
