Here's a mechanical solution I developed for a truck I'm working on, simply because I was tired of all that extra space between wheels and fenders that standard Lego steering requires. I found out that pretty much the same mechanism has been used by other builders already, so I'm not claiming to be the originator but I'm sharing this in case someone looks for something just like that. Its applications are limited given that it's very difficult to add drive or suspension, and there's some backlash that makes it good for floor only. But for my truck's front axle, this does just fine.

I saw it on your facebook and I liked it, it is something new that I want to try .

You may want to try something different that LAs to control it. They suit my needs, but they leave some slight backlash that may result in bump steering.

You got it right. One of the many benefits of the multi-link suspension is that you can adjust the scrub radius of the tire, and as such, make the car have better handling.

Thanks, Sariel. Realistic steering pivot points with LEGO has been an interest of mine for quite a while. It's nice to see a new method. Since you said you're sharing it for people who may be looking, I know that builders such as vmln8r, Ricardo Oliveira, and mahjqa have various designs for this, all for relatively smaller vehicles too. I do as well, and pics and video as well as a link or two to some of their stuff, are on my flicker account. Anyone curious can use the link in my signature below.

I'm planning to try this with steering links and adding suspensions, but I haven't tried it yet. It's not good to hear that is has slack even with liftarms... I will add tandem steering racks, hopefully it makes steering more stable.
