How did you solve the displacement problem of the two universal joints for steering? When I tried to build it with MLCad and calculate these angles manually, I didn't got correct results. So that the U-joint near the steering was never correct connected with the steering column. 
When I look at my real model, the steering wheel is a bit rotated even when the wheels are in a straight driving position. That's why I wonder, when I look at you picture...
