I'm sure you have heard the term, "INDEPENDENT FRONTSUSPENSION," but not many know exactly what it means. When one frontwheel of avehicle hits a bump or pothole, it will move up or down to compensate while theother wheel remains steady. Both wheels are independent of each other, hence that expression.
Watch the linked video, a German commercial for the Nissan Pathfinder,to find out exactly how this works. This gives a moving experience whichshould benefit your understanding of this piece of engineering.
Best explanation I've ever seen.
Those Germans have better ads than we do. ..
