HMMWV Rear steer

Is it disabled over a certain speed? Looks like a wreck waiting to happen with an inexperienced driver at anything over 25mph. Dont get me wrong it looks like fun and would be very useful on tight trails but no use on the street.

chevy trucks and suv's had rear steer for a while. i've never owned one but i imagine it would be a cluster later in the vehicles life...more ball joints and tie rods to go bad...what do you guys think?

It automaticaly disables over 25mph. The controls are easy, just a joy stick and a couple of buttons. The HMMWV allready has the mounts in place for 4 wheel steering. This just replaces the stock brace with a link to an actuator. It is hydraulic and is street legal.

can you explain how it is street legal? only reason i ask because i am under the impression that a mechanical linkage is required, and i wouldn't expect CA to be any less stringent.

also, i know in the video it said the rear steer is "locked out" via the switch. i would think that the way you say it "disables" is probably more accurate. is there any positive locking device to secure the rear steer linkage?

Rear steer is awesome! I have it on my rockcrawler and my transport vehicle.

Are there enough HUMMER/HMMWV units around to generate sufficient demand for continued development and production of a quality system? I doubt it. You will need to look to unlce sugar for a real payback.

Sorry to resurrect an ancient thread. Seems like this is the only thread I could find on it.

Has anyone here installed one of these? I was enchanted with this setup ever since I first got my M998 three years ago. The wife just gave me permission to buy it!

Only thing is I wish I had modified my diesel tank when I replaced it two years ago. It says it can be installed behind the diff? If so, so I still need to modify the diesel tank?

Not sure how it knows you are exceeding 25MPH so it auto disables. What does it tie into to sense that?

Not sure it is still available. I know you have to buy a new tank, and the pump separate, but not sure about hydraulic hoses.

IIRC, might have been Springer 1991 on the main HMMWV thread.

Haven’t seen him in a while (BUT maybe because I have him blocked).

It is very odd, @springer1981 does not show up as being active since May. I hope is ok. He is a terrific guy and gave me a lot of great advice that saved me tons of time and $.

The maker of this setup, @shannondeese has not been active for more than year either, but his web site is still online. I tried contacting him but no response.

Looks like I'll just have to keep drooling :drool:

Rear steer is not that difficult, and now that it is appearing in GM vehicles there’s a good chance that you will be able to obtain those parts in several months as they begin to show up in junkyards.

You can also review rear steer from other vehicles listed on the Internet with instructions on how to install.

IIRC, that other member who I have blocked placed his mechanism and then repurposed a turret control switch that he rebuilt to allow rear steer control.
