I've been reading up on full hydrolic steering (here and elsewhere), but it looks like no one has figured out how to make it work at highway speeds.

Is this still true, or have one of you figured out how to make it work? Is return-to-center the biggest problem? If so, could a coil spring be set up to counter the steering ram fix this?

It sure would be nice to get rid of all the steering linkage.

Ok, let's all share any goos site's / links related to Hydro steering.

Come on Daniel,

Spill it. How on the rear???

BTW i need just the beadlock for the 8 bolt rims. How much?? PM me

Hydraulic steering is fine on the highway, just takes a little more attention. I think the trick, if you need to do a lot of hwy driving, is to set it up so response is a little slower on the highway, but still provides the necessary power in the rocks.

daniel, how to do it on the rear? inq. mids want to know :D

For those interested, there is a very similar topic on the Jeep Board. If I could only spell, the search would have worked much better. Freeken dislexia.

Good stuff over there...

I was under the understanding that hydraulic stering was illegal for the street, because it doesn't have "return to center".

How about make use of self-centering coil-ver type steering stabilizers (like offered by Old Man Emu) to help out?

Then again, by the time you buy one or a pair of them, you could have just bought the correct self-centering orbital valve to start with :p

Well, I don't know what the area you live in, but up here these Bohemian farmers drive their frickin' combines to work! And they are fully hydro, they just can't go over 45 mph, which I think is the key. Just gonna have to buy one of those funky reflective triangles!

on my rig i don't see the fact that it does not return to center as any big deal. i turned the wheel one way i can turn it the other way. no biggy

When I had full hydro on my M715, I drove it to work a few times. Although it was not "Highway" miles, it was odd to drive at speed. By the time I got to work, I was about 3 full turns to the right more than when I had started. The steering seemed to drift to the left, I was always correcting by turning right. The way the cylinder was mounted was: Turning left- pressure on the rod side, right was pressure to the piston side. Charlynn orbital valve, stock GM pump,Parker 2" dia cylinder:beer:
