That's a funny vid.
It's nothing more than a Tahoe with a different body on it you know.
I had one in my shop a few months ago with a broken tie-rod, knuckle, cv-shaft, upper and lower ball joint and wheel. No body damage, so he wasn't in an accident - he must have broken it doing the same kind of thing that dude was doing in the video.
When you start working on one you realize it's really kind of a mickey mouse setup under there. All light duty stuff - like an independant front suspension. That works fine on cars, not trucks.
A lot of people would argue with me on that, and GM is being really stupid about it (even their 1-Ton trucks have independant front ends) - but they just don't cut it.
