I am new to this and searched but was unable to find this specific issue. I posted in another thread about bleeding the system. Once the ram is on what will cause it to work smooth in one direction then choppy in the other? It turns smoooth as silk to driver but jumps when truning to passanger. Any thoughts? Or do you need more info?

Did you take apart your box when you tapped it? Are you running a filter? Have you pulled the filter to check for debris?

what size ram? is it smooth when its pushing the rod in and choppy pushing it out? does it get better with the motor turning higher rpms? sounds like you may need a stronger pump or a smaller pulley or both. it takes more fluid volume to push the rod out of the ram then it does to push the rod back in

No filter. Just a taped box I got from another guy on NAXJA. Redid the broken and missing seals. The ram extends fine. It is pushing it back in that is choppy. So I guess I need to search for the jeep pump modification and try that?

I forget which port does what, but there's the one fitting that ends up being tapped really shallow over the passage in the box. If you screw that in too far you end up restricting flow on that one hose.

A lot of people confuse flow problems with pressure problems because they get in and just try to crank the wheel over as fast as they can and it doesn't feel like it moves easily at all. Pressure is when you're up against something and can still steer (this is the primary upgrade of a hydro assist setup). Flow is a measure of how fast you can apply that, which is where most hydro assist setups are lacking. Swap out for a smaller pulley and a higher flow pressure valve in the steering pump, make sure the reservoir can flow freely to the steering pump, and check the return line to the reservoir for any kinks or obstructions.

When you say a higher flow pressure valve in the pump ar eyou refering to the steering box itself? I'll check the lines and the fitting in the box. I think the port with the shallow tap. I think that is the line that is not turning right.

to clarify what vetteboy was saying... the shallow tapped hole is on the port running to the front of the box, so that would be when you are turning your steering wheel to the right that fluid is flowing into the cylinder. then again, i guess fluid has to flow in or out no matter which way you turn so it couldn't be that fitting could it?

No...this piece:

The stock one is pretty restrictive. PSC makes a modified one with larger/more holes.

Yeah, but it's acting as a high-pressure line in one direction and a low-pressure return in the other direction. Not saying that's definitely the problem but it could have a different behavior depending on which way the fluid is going.

That all depends on what way you have the ram mounted, right? I mounted mine opposit of what I have seen. I think.

Before you rip me a new one: I know I need a beefy tierod, I know this will not hold, and I have changed the mount to the tierod and the mount to the axle..

The port to extend the ram is in the top hole and it is smoth as glass. The port to retract the ram is in the shallow hole, and it is choppy at best. I am trying to get this done so I cna go to the crawl. So funds are none existent. I'll try and pull the fitting and check for restrictions. I have a friend that owns a junkyard here in town. Are there any pumps, and or pulleys that come stock on other vehicals that will bolt up and possiably help my problem?

There are some cheap/free mods you can do to the stock steering pump...I don't have the info at hand, but if you search you should be able to find it pretty easily. It involves drilling out a few holes in the stock valve.

If the restriction is at the box and not at the pump though, I dunno how much value you'll see from doing that. Mark a line on the fitting before you unscrew it so you can see how much thread depth you're using and compare it to the depth of the hole...that would give you a good starting point I think.

Pump right?

Will do good idea. TY all. If I dont get it working right today I'll plug the holes and run it without the ram for the Crawl. I'll just take extra part with me. :)

Pump right?

Oops - yeah. Stock steering pump, not box.

Found em'

Fixed I think. Apparently I'm an idiot. I put the lines in the wrong ports. :eek: Reversed the lines like a friend sugested that I thought was rediculous and its smooth both ways now. Will be playing with the ps pump mod at a later date though. I discovered the 91 parts pig out back still has the PS atatched to it. :rolleyes: GO ahead have a good laugh on me and at me! :lmao: :emb3:

You should mount the hose end of the ram to the axle so the hoses do not move every time you turn. that is why you dont see people doing it the way you did.

make new mounts and give us an update.

Ok I will when I return from the crawl and get the real tie rod in there. Appreciate all the help and advice back channel.
