hydraulic steering questions

looking at mad4wd.com ive seen that hydraulic assist steering costs more than full hydro steering.

Is there a disadvantage to having full hydro steering on a daily driver? is it not as safe on the highway? Keep in mind i no nothing about hydraulic steering, but i do understand hydraulics a little.

Full hydro steering is legal on the street but having considered adding hydro assist to mine and reading/asking about it, I keep reading/hearing that full hydro steering gives zero feedback and has a very numb feeling on the street. That's one reason when/if I do mine that I'll go with hydro assist.

One more thing to know, your front D44's steering knuckles are not really up to the force hydraulic ram assist can exert. Those parts of your front Dana 44 are actually Dana 30 components. I'm holding off on hydro assist until I can get a stronger front axle based on some very sound advice from a friend who's an expert in this type of stuff.

When you have a choice, buy American made.

Assist has more parts.

No disadvantages to full hydro if you build it right and pay attention. If you patch it together or lose pressure you can be SOL when the steering stops working.

My PSC full hydro has feedback and return to center. On pavement, it feels a lot like factory steering (only better). On trail, the benefits are dramatic and obvious. ymmv

i need to seriously address my steering, i basically still have the stock steering on there and hydro assist will be over 2000 when i get all the parts together where as hydraulic will be around 1300 ish. and then when i get a bigger axle it will be easier to modify to fit the bigger axle. i will just have to be aware of it while offroading.

And as far as a hydraulic system goes i dont screw around with hydraulics, i have a lot of experiance around heavy machinery and if you dont do something right it can kill someone so theres only the right way to do it.

if you're talking about Blaine, from what hes told me hes working on a way to attach a ram to the passenger side knuckle on D30 and D44R's for a hydro assist setup. in my "HD Steering components" thread he talks about it in there.

I forgot about that. Larry was going to work with Blaine to put hydro assist on his currie steering setup while he's down there this week iirc.

Double ended ram is the way to go though for the simplest setup and best overall performance.

I thought full hydro steering was illegal in at least some states... you'll certainly want to look into that.

^I wouldn't listen to what I say. I don't know what I'm talking about. Please use the search feature.

PSC's assist is only about 1300. Just wait until Blaine comes out with one that will bolt up the the Currie.

Nice first-hand information, I based my thoughts on the articles I read while researching it. Thanks!

Yep, it was Blaine who advised me to hold off with my present D30's configuration.
