from what i saw it seems like it would be an easy conversion. of course you would need a H1 to start and that's not the cheapest truck to be playing with.

I've heard of a few hummers on the HML that have done this mod (there's a video floating around somewhere). One guy was trying at one point to put together a kit. It's seems pretty cool...might help reduce those 10 point turns on tight switchbacks!

Hey chief...Hummers (or atleast the Humvee I drove) turn tighter than a stock Jeep TJ. Something like 34 or 36 feet.

When Toyota built their version of the Hummer, they installed 4wheel steering.

Is it even a hummer? I'll just go ahead and say no or it might be like calling an FJ40 a Jeep.
Where could you mount the stuff needed for rear steer in the back of a hummer? Swap in a whole front setup?

hey focker, it's just a game...
yes I know what the stats are (27 vrs 37 ft) I've owned one for 4 years. My point was that a vehicle more than 20 inches wider than a rubi or taco can benefit greatly from a tighter turning radius...and rear steer is probably the only way that will happen. When you turn all the way to the stops the outer cv angles are close to max -- that combined with too much skinny pedal is, uh, bad.
I'd think that with the rear geared hubs/a-arms being the same as the front, it probably wouldn't be too difficult to make work. But it's crowded under there so finding a place to put all the new stuff without losing the rear tank or affecting ground clearance might be tricky.

:laughing: It's fine, I just read your response wrong. I agree, they could be better with a tighter turning radius. I didn't have enough time to drive the one I had access to realize deficiencies it had. I broke up with that gf.

hey no worries.
I love wheeling my truck (97 open top) and am ashamed of all the bling/chrome/bs people usually put on them as well as how few actually wheel. It's a tractor for gawd's sake -- get it dirty.
anyways...I'll do some searching about this subject and post up if I find anything worth sharing.

Not sure about the civy stuff as I only work on the military stuff, but you would be able to fit a double ended ram right in front of the 1st rear crossmember, and run the tie rods to the hubs. It would be a cakewalk as there is plenty of clearance on the mil versions. Not so sure how things are packaged in the civy world.

A guy I rode with in Dayton tenn. had a green h1 with rear steer. It had a turned up 6.5,propane injection and 39" iroks...cool hummer, nothing I'd want and still got spanked by close to stock jeeps, FJ's etc...but heck most of the group were hummers and I will say they all had fine looking co-pilots.

all vehicles have strengths and weaknesses, but a near stock fj or jeep spanking an h1...hmmm. Where were you wheeling? I've wheeled with alot of jeep brothers in the Big Bear/Arrowhead/Moab area and the reaction is usually "holy shiite, you made it look easy" or "I can't believe you made that."
as far as the rear steer...The guy doing the current mod looks to be about 60% done. Looks great. I don't think I'd ever do it unless it was a kit...I'm not that mechanically inclined to do it from scratch.

This modification has been done before, and there are a couple of people working on it now as well; it is on my short list of future mods.
It is just about as easy as described above -- replace rear radius arms with tie rods, install hydraulic ram in the middle. The hard(-ish) part is routing the controls and hydraulic lines to the ram.

I want rear steer! I feel the need to crab out of a bind ,or a tight turn. I have been wanting to do this for a year. Checked out hyd front steering and would like to see what others have done...to steer me in the right direction.

Definitely not a hard mod as there's lots of room through the tunnel. You HAVE to figure in a locking pin to hold them strait for when you road travel too, or you'll have issues from legal to dangerous. Ive worked up a rough budget and because the front and rear is just a flop, it can (in theory) be done for around $700 (all hydraulic).
Ron,
There will probably never be a kit unless one of you guys does it. It's not worth the liability if you're only gonna sell 20-25 units....if you're lucky. More than likely to be a freely exchanged parts list. CumminsH1, or RD Travis would be the best guys to set you up if you want someone to engineer it. My crap is all guesswork and booger welds. :flipoff2:
