I couldn't refuse the title. As if Mike's family wheeler was good enough with a full Clayton kit he's adding hydro assist now too, I hate to see what the CJ is going to end up like. Anyway just thought I'd show what a steering geabox looks like disassembled and where you can tap it for hydro assist. Mike it is ready to go. Call me tomorrow.

Bare Box :biggrin:

Nice work Sean. :cool:

I'll be calling you for measurements to locate the drill locations soon. :wink:
 
How big a project to rebuild the box? I'm going to do mine when the motor/trans goes in.
 
Took me an hour or so do disassemble, that is because Toyworx's soaked the thing in salt water first, not true but is was rusty. And I reassembled it in less than a hour. I'd say about 2 hours start to finish. That doesn't include to removing and installation on the truck.

WOOOHOOOOO!!!

SWEET!

Thanks again Sean!! I'll ring you in the AM.
 
Sounds easier than doing a t-case or 4 speed tranny.
hmm. What kind of ram do you need to match this?
 
Beaker,

Talk to Sean about specifics, but it's not so much the ram as it is the pump. You ABSOLUTELY have to upgrade the pump and resevoir in order to do the ram. The stock pump just won't keep up. I got my pump from PSC, and will be running the stock resevoir and no ram for now. Next month I'll add the remote res and the ram.
 
Beaker, it isn't that easy, but can be done with some good instructions. There are quite a few parts inside including 24 balls for the ball screw. I've done a few of them. As for the entire system, what I've read and learned is that it as much about the flow and pressure as anything. I use a 1.5" bore x .75" rod cylinder, then a PSC high performance pump. Everything seems to work well.
 
I know quite a few people running stock pumps with hyrdo assist. the key is a small ram (1.5" ) and a cooler and reservoir.

Also depending on what you plan on doing with your rig I would reccomend a smaller shaft. this allows the steering forces to be closer to balanced. pretty important when you drive it on the road.

I understand the worry about the shaft bending but I know quite a few people that run em and have no lack of hardcore. Cory at wayoffroad and Lucas Murphy.
 
I didn't mean to imply that is is easy, just sounds like something I would feel comfortable attempting. I've rebuilt motors, tranny's, transfer cases, etc.

I patched the frame around my steering box (badly cracked) and am very interested in reducing stress in that area since I'm working up a major increase in tires size.
 
Nicely done. I was just reading a thread about this on NAXJA. Guy did the research and you can get the parts for about $100.
 
beaker that is why I said with the right instructions, I'll look for the link and send it you.

$100 sounds close for a price, that is about what I spent but then I did the PSC pump and resivoir which added $$$.

My recommendation to anyone who is going to do this is to buy a complete rebuild kit and replace as much as you can while the box is apart. That in it self will show incredible results on a 10+ year old unit.
 
Well I've learned a little more than I thought I this rebuild. Thanks to a f*&k up, Toyworx's and I now know how every part of the gearbox works. I appreicate your patience Mike. We will get it staight this week.
