I've been looking at how to do a properly done, realistic road grader for some time now, from Technic LEGO, and I've become stuck trying to properly emulate a realistic design for the front steering. As anyone who's seen a road grader knows, they have a true three-dimensional seering system. It can lean to one side or the other, turn, and handle driving over drilled runs with ease. Larger graders, especially, are articulated using hydraulics at the cab-blade beam joint, making really tight 360 turns possible. As I understand it, in order to properly build the front end I need to use some sort of universal joint assembly for the steering on the front wheels. Does anyone have an idea how to do this in Technic? Has anyone attempted a road grader in Technic? The few models I can recall LEGO themselves doing didn't address the steering aspects needed.
