Sag box leak!!!

My guess is that he isn't in the market for any more mods until he gets everything working. Besides I doubt he will run tires big enough to need hydro assist with Toyota axles.
 
Hydro assist will help out a lot in the rocks even with 35s. When I went to 38.5s, I had to have it. (I run toyota axles...)
 
Yeah... Maybe later down the road, but for right now. Just wanna get everything working right and enjoy it finally!
Gonna do the sag box this weekend!
 
You can always tap it now while you have it apart and just plug the holes with and NPT plug (I think that is what the guy did in one of the links I posted above). That way you do not have to dissassemble it later on to do it. I wich I would have done it when I rebuilt my box, but I was impatient and just put it back together.
 
If you want to port it then do, if not, it's a cheap mod later on that either you or West Texas can do.

I just picked up one of the Surplus center rams for Bob. Worlds best steering stabilizer ;)
 
They do make badass steering stabilizers. No more steering wheel jitter.

Huuuummmm. I have all the stuff from PSC to add hydro assist to my truck. The PSC Sag setup turns 36" Swampers so well I've never bothered to install it though. But I do get some gawdawful Death Wobble from time to time.

We had a blow out on a 38 that was up front while my wife was driving doing 70mph down the freeway. Having that ram probably saved our lives because it kept the tires pointing straight and didn't rip the steering wheel out of her hands. So a big AMEN to Mace's comment!

That'll make you need to change your shorts! Glad it worked out well!
 
Alright... The safety factor had piqued my interest....
What rams did you use (pn)
How about fittings and hose?

I was thinking strictly in terms of turning ease, which that sag box really does a nice job in comparison to the 60 series ps set up.
When I engaged 4wd, that bitch was markedly harder to turn.
On matti... I don't even realize that I have an auto locker in it.
Now you bring up the stabilizing benefit... That's even more appealing in light of boots story.
 
I got that same box the J20 (A-1 Cardone Reman) and i put a big cooler on it.

Keeping the Fluid cool had made a world of difference.. and the Larger Bore Box helped too im sure..

I still want to do assist, but dont want to loose the quick responsiveness that i have without it.
 
There is no reason to lose the responsiveness. It's all about a balanced system
 
Bigger the hose the faster the response. ;). You do want to run a large cooler on the lines. Because if you get the system hot it will ruin your pumps tank seal. (I found out the hard way) Run no smaller then 3/8 hose 6n I believe. I suggest 1/2 . You will also want to do this upgrade.

Your pump will do in the stk form but this makes a difference. Mini truck axles use a 6" throw cyl. I dont know how long your axles are. I know the Dana at 60" wms to wms uses a 8" throw cyl . Double action on both.
Here is a pic of the one on my CJ5 . Same steering box as your FJ40 though

I've got fj60 axles...
What do you do for a cooler? Where's that mounted?

Not something I can do right now... I cant afford a stick of gum right now!!!

Sort of, you can't move more fluid than the PS pump can provide. And you are still limited by whatever fittings you have put on the box (commonly 6an). You will also potentially cause a ton of cavitation using those right hand angles like you did. The longer curved fittings tend to work a lot better (but are obviously harder to package).

The main thing that "slows down" the system is a big ram. the bigger the ram, the more fluid is necessary to fill it. A 2" ram takes more fluid to move the ram back and forth than a 1.5" ram. If your pump cannot keep up, your steering will be sluggish. The sluggish feeling is because the steering box and ram are pretty much working together as a pair. If one can turn tighter than the other, the wheel will lock up temporarily. I had to run my 40's ram disconnected once. To turn the steering wheel you would put a bit of pressure on the wheel. This would start the ram moving to either the fully extended or fully retracted position. I was not able to turn the wheel until the ram was finished moving because all of the fluid was rushing out of the steering box into the ram. I had no assist.

Running a 1.5" ram will provide assisted steering without the lag that the 2" rams sometimes have.

The width of the axle has no bearing on the amount of throw that the ram needs, it is all dependent on the length of the steering arms. Short steering arms = short throw, long steering arms = long throw ram.
 
As Mace said 1.5" ram. But to clarify(sorry Mace gotta be a bit of a smartass) Longer the axle the longer the steering arm.:D No disrespect though Mace you throw down some awesome tech. Its a little more your solid mounting point to the mounting point on your tie-rod and distance of lock to lock . But anyhow on your cooler you dont need a big one . I went a little overkill on mine. I used a power steering cooler off a 4610 ford tractor because it was laying around.I mounted it in front of the radiator . Any were that you can get airflow will do. I only have about $15 in fittings in my whole system .I picked up my hoses and cyl. out of a tractor dealer boneyard. The hoses were out of there Ops they messed up bin .
Here is what I figure for the guy that wants to pay retail .
$100 for new cyl. $50 hoses and fittings Junk yard steering cooler.???? A lot of cars and trucks have them or a small trans cooler would also work. Just remember to clean them out good.Oh I almost forgot 1/4"NPT tap. Remember to do the deeper hole first because your going to have to cut some of the tap off to get the shallow one threaded properly. Also another cheap bit of tech . If you are not running a high capacity reservoir a cheap trick is to add a short piece of 1.5" hose (P/N 1030 napa) and a cap and bung to the fill neck on the pump. That way you don't get the spill over and lack of fluid when turning and wild angles.

What?
 
60 axles and mini/40 axles share the same steering arms. As do any of the hybrid whatever length you want Diamond Axles - Front/Steering Axles. Wider WMS axles does not make for longer steering arms ;)


At one time I had OTT industries make me up some super short steering arms for my 40. After that, I only needed a 4" throw steering ram.
 
You don't have to have a cooler either. I don't run one and I've never had a problem.

Whoops lack of careful reading made me look like a dumb ass . I dont know why but I had steering rod stuck in the brain. You are correct and I am going to hide in shame .....
