mine has full hydro steer.
it WILL steer with the engine off
it only cost me about $175 or so for the ENTIRE setup(ram, vavles, hoses, cooler)
works great, yet to break ANYTHING
a few of you guys saw mine at zukimelt, i have since prettied the rig up some
parts i used out of a JD combine
it has held up fine pushing 38" tires
the rocks dont bother it, and it does not jerk the wheel at all.
hell, as some of you know, i acually run a steering wheel spinner.
its simple, dirt cheap, works great, i love it
i wouldnt use it on the street, but i don't care.
