 i have seen images like this before of vehicles flexing but i was never sure how it worked. how is the suspension, rear bumper/ gas tank and body all flexing at different rates? i just don't get it? ![]() homepages.wmich.edu/~a2steffe/blazer flex.JPG[/img]

His right rear tire will stuffed up in the fender like his front left one is. Forced articulation. What's not to understand? Heres a old pic of my 4runner flexing in a ditch.  I finished the paint job since and real need to get some new photo's. |

so when your 4runner flexs the frame and the body seperate at the rear like that truck?

i have heard of people putting rocker arm spring from an engine on top of the body lift bushing so that there is some play in them with the body. but would that really allow that much movement?

I am not sure why there is that seperation either. Everything that is connected to the frame will flex when doing that.

this looks like the key is a solid axle, and he bolted his spare tire, hitch reciever to his rear axle? if you look at his exhaust it's pointing at the same angle as his body, so that would mean the frame is the same angle as the body, since the exhaust hangs from the frame...frames don't twist, unless he custom made this one to articulate in the center.

so you mean he might be using a subframe.

My question is....I see were the front of the rear leaf hooks up, but where's the back?? Shouldn't it be stretching just as much in the back is it is in the front.....? I tried zooming in in photoshop, but I can't see anything.....I think there's no telling how this guy has it set up.....i'm sure it's not your german engineering .....also i understand about the exaust hanging from the frame....but I don't see where the exaust pipe comes down from the frame....and also just guessing if when he wasn't flexing....that exaust would be almost dragging the ground.....unless he has a hellacious custom body lift |

my first thought is that the suspension cannot be that complex...it's a GMC after all . but the pic sure makes it look like it is. there could be a sub frame...but ya can't really see much.... it's the devils work  |

it almost looks like he just has a busted body mount or something, so when the suspension articulates and tries to twist the frame, the body just lifts off on the corner... i don't know, maybe i'm wrong, but....  i think the red line is the frame, and the blue circle is where the rear leaf pack attaches to the shackle/frame what do you think? |

i resized the picture, might be a little easier to see...  whatever it is, i want a setup like that... that is, as long as it's SUPPOSED to do that... |

man, the pictures are sometimes working and sometimes not.... if they don't work for you, you can right-click, choose properties, copy the URL, open a new explorer window, and paste the URL into the address bar and it'll work that way

...busted body mount or something... looks like the best answer... but why is the exhaust at the same angle as the body? as far as i know exhaust hung from the frame not the body. |

Yeah thats some weird suspension-er-body um setup.
I have seen vehicles where they mounted a different body to a frame and used a half leaf spring to mount the body to the frame. It allowed the body to move around on the frame when articulating. Still not sure how well it worked but I have seen it. I think it was an XJ jeep on a full size chevy frame.
But I don't know why this GMC is doing it unless its just some messed up body mount that is rocking the cab over when flexed. I would say this truck is the exception to the rule.
