    full hydro steering for a street driven jeep

    Working on completely rebuilding my TJ into an LJ. I am currently stretching the frame right now but was thinking about steering. I have a 6.0 ls 4l80 and atlass 2 spd that I will be running. Ford sd 60 and 10.5 sterling. 3 link front and double triangulated 4 link in the back using brackets and trusses from artec. I have 37X13.5X17 BFG KM3 tires. I will be pushing the axle forward some and I know if I move it more then a couple inches the stock steering box will not work which from what I understand isnt too strong to begin with. How bad of idea is it to run full hydro in a jeep that will see lots of street driving and highway driving. I was planning on doing at least hydro assist and it would be a lot simpler to just do full hydro then hydro assist and make all the steering linkages and try not to get bump steer.

    For one, its not street legal I don't think. Perhaps that depends on location. Reason being is you lose all steering capabilities if your engine shuts off.

    Second, the no return to neutral would throw me all off.

      When I did my 1 ton swap on my LJ, I kept the steering box that was ported for hydro assist and switched to a dual ended ram as my tie rod. I went with the 2.75" ram from PSC with their pump and was over all pretty happy. Kept me street legal and turned 42" pretty good. If I were to do it again, I might drop back to a 2.5" ram. The only time I noticed slow or sluggish steering was when I would whip into a parking place, realize I didn't quite make the turn, throw it into reverse and cut the wheel opposite to back up a bit. Right there I could sometimes turn quicker than the ram would allow. If I waited a split second, I could turn and pull in. I figured I was asking max pressure/volumn while at idle where as on the trails I might be carrying some rpm.

      I did eventually go full hydro, replaced steering box and put orbital in same spot. I dialed in appx 8 degrees of castor. I did drive ok on street, was really twitchy at higher speeds. Would not consider it overall to be that safe to drive. I kept the vehicle registered and passed inspection each year and pretty much only drove to edge of neighborhood to gas station. We did go to Moab and Colorado several times but I always tried to stay on side roads and keep the speed down.

      I would not recommend doing full hydro for street and daily driver duty. I did not feel comfortable at speed.

        I was figuring that was going to be the answer I got but figured I would ask.

          Bullshit. Please show me a statute anywhere that says that, or better yet, proof of someone actually being cited for it.


          As for the OP, it all depends on how you put the system together. It is really important that you match your components to get you what you want. I have driven full hydraulic steering on some of my buddies buggies with no issues at all at speed. I highly recommend reading the Billavista article on the subject: http://www.billavista.com/tech/Artic...ble/index.html

          The system that JR4X put together for his 4500 cars seems pretty sweet, but people seem to be having lots of issues when the components aren't perfectly matched or there is slop anywhere in the system. It maintains the mechanical connection and feedback of an assist system, but with the power of a full hydraulic system and keeps all the stress off the steering box.

            Ease down there hoss.

            When I was installing full hydro in my samurai, I had people lining up telling me it would make the rig not able to get a sticker. Buddy of mine had the same issue. Saying its not road legal because if the engine cuts out you cannot control the vehicle. Either way, we buggied out or rigs so they never got a sticker anyways. But yea, that's why I said "I don't think". Its just what I was told. Just something to consider before you go ahead and go through with it.

              It's nothing personal, but just because it is "what you were told" doesn't mean you should continue perpetuating urban legends. There was some discussion about this in the TP, but the illegality of bead locks and full hydraulic steering are some of the biggest misconceptions in the wheeling community. In fact there have been bounties put out on the old site for someone to come forth with an actual statute from somewhere saying these things were illegal, or evidence of someone having been cited. As far as I know, no one was ever able to come up with either, and the bounties were never paid out.

                None of this is true

                  does "welded steering linkages" fall into that category as well?

                    Huh. Did not know it was that hot of a topic. I had people hollering at me about it too.

                    Apparently not. I stand corrected. I was just going off what I had been told in the past.

                      1- never seen the "law" produced

                      2- mine steers with the engine off

                      3- mine returns to center.


                      Do you have proof to back any of your claims or are you just spewing incorrect information?



                      With that said my truck is driveable but I wouldnt trust anyone else to get in it and not kill a bus load of nuns. I vote steering box with assist.

                        I would think any type of steering would somewhat want to return to center while driving, no types of steering actively power themselves to the center, do they?

                          Take a few steps back and read some of my follow up posts. Also in my post I said "I think". Meaning, not 100% sure. Hate to see the guy go full hydro, and then not be able to get a sticker. Merely suggesting he check out the laws read. Jesus. Have a beer or something.

                          My rig didn't steer with the engine off.

                          Mine also did not return to center.

                          I was running a PSC pump and a TSC single sided ram, so perhaps that was the cause not going back to neutral.

                            My Samurai did not. You turned the wheel, and it stayed there. There were some times I had to drive a half a mile or so on the roads to the trail, and it was freaky as hell. It was also a single sided ram, so perhaps that was the cause. Do the double sided return to neutral? All the guys I wheeled with had single sided.

                              There are different types of valves, some do not respond to outside forces (no reactive) and generally drive worse.

                              Return to center has more to do with alignment than the hydro steering iirc.

                              I've had 3 different full hydro set ups, all single ended (which is supposedly worse) and 2/3 were OK on the street.

                              I'd really like to try the servo steering at some point
