I was reading a article in 4 wheel offroad today about the new 4 wheel steering in the new GMC's. If you ask me, I think it is a load of crap and GM needs to redesign there rack. It's just a added cost and more crap to break. It looks like a good design, it's a Dana 60 axle witch is plenty srtong, but they bent a link while putting it through pretty hard test. But if GMC would put some thought in there rack design, there trucks might turn worth a damn. Here is how they compare in turning in a circle: Ford Excursion-46.8 ft Dodge Ram-46.7 ft GMC with out Quadrasteer-46.2 ft Tundra- 44.4 ft F-150 40.5 ft Jeep Grand Cherokee 37.6 Ft Altima 37.4 ft GMC with Quadrasteer option 37.4 ft it's a big improvement from what it is without it but if you ask me, they just need to put more idea into how there trucks turn. One more thing to break on there trucks and add's more to the cost.
