Hey Guys!

Great thread. I have read through the first 3 pages, and it seems like everyone has been happy with the mod, if they can get the small bugs worked out.

I am posting because I am would like to know if anyone "has or could" take the highsteer arm off at the pitman arm, and try steering the truck with no mechanical linkage?

I am not an expert (by any means) when it comes to steering boxes and pumps and whatever. It just seems that there is enough force there to run a 2"x8" ram on its own for at least light duty work. Before it gets brought up, I am completely aware are the safety factor and have no intentions of driving the rig on the street. Thanks for any help I can get.

myabe im mistaken, but thats full hydro is it not?


this is what tractors use, i know its what our TUGs at work use, i somehow snapped a knuckle off the ram before.....

Cool!....

Thanks guys! Thats what I needed to hear. Yes, its full hydro. I just didnt know if the tapped stock gear box could act as a steering valve, without the mechanical linkage creating resistance.

I will post the pics and info on the build in the rig section in the next month.

You guys are great! Thanks again for the help!

hey anyone know if a 2" bore ram is too large for the toy pump? I can get a smoking deal on a 2" bore 6" travel ram, most kit ive seen are 1.5 but it'll cost me almost double for that size.

2" bore ram depending on the shaft diameter will probably be really slow with the Toy pump. A lot more volume to be moving in the ram.

think i trashed the steering box today. i was out playing and pull apart a hydro hose at the ram. for a trail fix to get off the trail i looped the in and out of the box togeather and pulled the ram off.  box got hot and the steering would lock up then release and work. i went and got a new hose and started playing again. the steering i thought had air in it so tried to bleed. started driving and working it but it would stick and not turn.did this for 30 min sticking ,grinding, hard to work , then nothing. steering wheel spins with little or no resitance.  question did i cause this because i hooked the two tapped holes togeather and drove on it?   still had fun and safe trip today,

sounds bad whatever it is..something is probably burned up (seals or pump or something)

I keep a couple (cap-off) plugs for the ports on the box in the toolbox in case something like that happens. I think they were less than a dollar a piece. I would advise the same!

Hey guys, OK so I did all the mods(larger reservoir, drilled restrictor,cooler) and it came out great thanks to this thread. I just can't seem to get the pump to stop squealing. It's not to loud, just annoying at this point. I've tried to bleed the system several times with and without the tie-rod attached to the pitman arm.
 any suggestions?

And heres Rick's pics from the same thread showing the work done to the 80 box.





Great info Rick. Thanks for letting me add this to my thread. I hope to be borrowing this info as I will be doing a 60 box in the coming months.  :thumbs:

Is there any reason the IFS box can't be tapped similarly to the 80 box, rather than tapping directly into the vein?  It looks like the basic design of the boxes are the same, only bigger and reverse rotation on the 80 box.  If you look at the first two pictures, and compare it to the pics in posts 19 & 17, the "end cap" area looks to be the same design, w/ a seal area (shiny part around the end of the inside of the cavity) and the vein going into the recess at the end where the 80 box is drilled.  LMK if that makes sense to anyone other than me.  Seems like you'd save alot of worry

I pulled the box and began to disassemble it following freds40's instructions from the Marlin board. I got to the step saying to remove the 10mm plug and the contents behind it. The plug was difficult to get moving but it came free and I don't feel like anything sheered.

The issue is, it wont come out... Pictures show how far it came till it stopped...





Was it hard to get this out for those who have done this? Am I fawked and need to look for a new box? Any help is appreciated:flipoff2:


Freds40's instructions---

If your box has the centering valve, use the 10mm allen wrench to remove it. There is a valve, spring, and almost a cylinder that need to be removed. If you don't have one, skip this.

That 10mm plug is a pain in the butt. You can tap on the top of the plug gently with a hammer if it is starting to round out. This will tighten the fit with the allen wrench. You can also grind the end of you allen wrench flat so that it sits deeper in the plug. I would then recommend putting all your weight straight down on it while keeping the wrench straight as you turn.

Good luck.

I see what you mean. It may take two people. Gently pry on opposit sides with small screw drivers on the treads while some one turns the allen wrench. Pry enough without damaging the threads. If I remember the o ring gets hung up. Just takes some firm but gentle pressure. :thumbs:

PSC makes a pump kit for a Toyota 3.4 and I have read that the 3.0 PS pump can be reused during a 3.0 to 3.4 engine swap. Has anyone tried the PSC 3.4 pump on their 3.0 yet?

ha ha ha.... enjoy

I put a few in there with a grease. then I start working the shaft in there. and as the last ball is at the edge of the box I put a new in. then turn a litle, new ball, turn more new ball...

just before you start, contact the dealership and make shure how many the balls should be, I think they are 52 but it has been a few years, so make sure before you start. I once lost 1 or something and I got an explodet view of the box, after a week or something, and that was scary

Thanks got my box tapped and everything was good for a couple trails. Then my ram assist tore off the mount on my axle because of my lackluster fab skills. I didnt notice the ram mount broke for two turns and then my steering box blew out on what i think is a release valve ( i believe there was a ball bearing in the whole ) in the picture circled in red. Has anybody seen this and is this something i can fix or should i just grab another box at the junk yard?

I used this thread to do this today. I just got the box saturday (2 days ago)My plan is to buy the high steer arms in the next 2-4 weeks (hopefully) depending on $$ I installed plugs in the holes cuz I wanted the box done before I install it, but it might be several months before I can get the ram, fittings and hoses. When I do get them I will that much more ready. The only problem I had was the threads tapping deep enough... But I think I got it. Great write up "VERY HELPFUL" Without this thread I would have never even tried to tear the box apart. Thank you very much!!!

You may call your local rebuilder and see what they say. I would just get another box.

Most people have a tough time getting enough threads on the top port. You can buy a bottoming tap to get more threads in there. Most places like lowes and homo depot do not sell bottoming taps though. I just bought a second tap and took the grinder to it effectively making my own bottoming tap. I ran my regular tap first and than my home brew bottoming tap second.

After tapping both holes, I cut a quarter inch off of the tap, and ran it in again. It seemed to make the threads that were cut the first time, deeper. It wouldn't bottom out. I think I should have cut off less... But the plug went in 3 turns and I'm prity sure it won't leak... You think??  I tried to buy a bottoming tap but the hardware store that I went to didn't cary them.(Park Rose Hardware/Best in town)
