New insane question
Sanity has taken leave of me again, not that this is either an unusual or an irregular event.
Has anyone here ever done a 4 wheel steering system? and into the next level Has anyone ever Heard of someone making a 4 wheel steering system on a full independent suspension? I've seen the Dodge Stealth/Mitsu 3000GT VR-4 setups, but those are a little...less than I want.

Don't have any info on it, but here's a screen cap of a 69-72 Blazer from a video clip I think I got from here. Sorry for the bad quality, but its the best I can do.

I did it many years ago on an 87 Chevy truck. I belonged to a friend of mine. He bought this 350 4spd LWB truck specifically because of the change coming in 88. The truck only had 40 miles on it in stock form. It was lifted 12" with a Skyjacker kit and a 3" body lift. 18.5x44x16.5 SuperSwampers went on too. This was in the first weekend of the trucks life. A few months later he came to my boss looking for something "new/different" and he tried to talk him into a B&M blower...........To which I said... "Why not do rear steering?"
They both looked at me like I had lost my mind, followed by "Why not?, can you make it work?" ........Sure. It was actually a fairly simple swap. I used a Dana44 front end from a donor truck. I moved the rear springs inward, to be under the frame rails instead of outside them, using stock front frame brackets and some reinforcing. This allows the use of the front axle with out modifying the spring perches. It also gives you the clearance needed for the wheels to turn. Two birds with one stone. The driveshaft had to be lengthened to reach the offset (from center) of the pinion. The steering was accomplished with a hydraulic cylinder that was installed into the factory mounts for the steering stabilizer. The pump was mounted to the frame up near the cab. A simple "on-off-on momentary" switch was used to steer it. I welded a bracket to the axle housing that was directly under the arc of the original steering arm. This was used to "Lock" the rear wheels in a straight forward position. There was also a key switch to cut-off the pump motor. This was a safety thing because this was a farm use truck that had many different drivers, he would let anyone drive it with the steering locked. I changed to an adjustable proportioning valve to compensate for the disc brakes on the rear. This truck ran 10s of thousands of miles over several years like this with 5.38 gears and never had a problem. It went to the Jamboree in Springfield 4 or 5 years in a row. It was a blast to drive, though only 3-4 of us ever really mastered it. I did another one a year or so later. This one was a Blazer and the owner insisted on the pinion being centered. It was far more expensive that way but it worked just as well. Personally I don't see the need and the cost of axles and the labor involved to cut and weld the housing added to the bill. |

![]() So the system would have been like the ones the monster trucks use right? Full left -- Center -- Full Right? That's an option, but my hope is to do something more linear, although the using a 4x4 front end was something I hadn't thought about... Quote:
I'm assuming that this system wasn't in need of a speed safety switch since it was a manual use correct? Quote:
Ever seen anyone use a progressive (like the Delphi system I suppose) steering for the rear? Thanks for the info longhair and everyone else for the links ![]()

The thing was fully manual. It didn't automatically re-center itself. The switch was a momentary that stopped where you left it. It was not connected in any way to the front like the new trucks. It was fun to drive holding the steering wheel straight and truning the rear wheels like a forklift though.......really freaked people out. The physical lock to the wheels was done by putting a bolt through the steering arm into the earlier mentioned bracket. It couldn't be locked or unlocked on the fly. The lock was mainly used for longer "highway" trips, like going to Springfield, and for daily work. It would have a tendancy to drift a bit to one side because of the crown of the road if you drove very long w/o bumping the switch to bring it back to center. It was unlocked for weekend goofing/cruising etc.
This truck also had a tilt bed that tilted toward the passenger side. It was too high to be used as a "practical" dumptruck so the side dump was just another "show" thing. It was wild at the gas station though. Can you imagine a truck that tall coming at you on the road at an angle with the bed tilted toward you too? Good thing we were in a small farming town ![]() The bumper height laws forced the sale of this truck. From what I heard later the new owner destroyed it. He broke an axle and replaced the entire housing with the original from the truck. He later wrecked it and proceded to tear it up as an off-road beater............ I'll have to see if I can find anyone who still has some picks of it. |
