How feasible would it be to think taking one of the gm half ton truck quadrasteer axles (circa 04-05) and mounting it up under a thirdgen? I'm not too familiar with them but I was thinking about this while talking to a quadrasteer owner the other day. I'm fairly certain you'd need to cut out where the back seats are, or at least a chunk, to fit the steering rack. But I guess that means a torque arm would be hard to mount. Flip the knuckles and mount the rack on the rear? Then the panhard becomes an issue...

I guess I'm just babbling. Laughing

GM actually made a few demo thirdgens with rear steering. From what I remember, they flipped one on the skidpad, so they trashed the whole idea.

I remember seeing a pic of the 1 they kept on a rack and showed the rear wheels turned.

Is this a passive type steering?

If so ditch that idea. Everyone I've ever known to have passive rear steering, when a component fails, they remove it. It's a bad design and bad idea.

It's ECM-controlled? How are you gonna hook all that up? Also, how is this:

...going to ever physically fit under your car? Not to mention the width. And it's not like you can just whack a section out, reweld the tubes, and cut a little off of the splined ends to narrow it down, either.

It took GM several years to get the software right. The hardware wasnt a big issue. It's basically all front end stuff from a 4x4. The big problem was knowing when to turn how much while keeping the vehicle stable.

My wifes brother in law has a GMC 1/2 ton with it. There is no way in hell you could fit all of the hardware needed for this diff in a 3rd gen. It is amazing what GM stuffed under those trucks, it's more congested than if they had put independent suspension in it. The rear end is also about 6" wider than the regular truck rear end. If I remember correctly, this was promoted as a towing aid and the diffs were all 14 bolts. They are huge.

Not that I doubt you Ian, but where did you find that info? I had looked before on the internet and couldnt find anything. I remember the info from a hotrod mag, or some type of mag.

This sounds like a good way to have your car torn apart for a 5-10 years..

So instead of messing with all that electrical and software crap.. you could put a steering wheel in the backseat and let Dirty Steve drive....

Or not. Laughing

I love the quadrasteer silverados. Parking lots and U-turns are easy as pie with those trucks. It also eliminates the need for making a 3 point turn to get in on a rack. I can ask some of our techs some questions about the whole system if anyone wants.
