I searched this and came up with a couple old threads with broken links. Does anyone have a link to a write-up on how to rebuild my steering box? It's leaking like a sieve. Also, where should I get the seal kit? trdparts4u has it for $82. Is that a good price? Any other sources? Thanks for the help! Vehicle specs are in my sig.

 

A few months ago the box on my 84 decided to start leaking on me. I looked at different rebuild kits and seal kits, as well as reman boxes from different sources (which are expensive as hell). In the end I decided to ebay a used box for about $150. Works great, and it bolted right up. From what I have read, some special tools are needed for rebuilding the boxes, and there are a lot of loose bearings inside if you take it apart wrong (trust me...).

 

Factory Service Manual would be helpful, or the old link is cached here:

Well, yeah, I know I can get a used one. But, every IFS box I have looked at lately leaks to some extent and I would just like to learn how to do it.

 

Thanks Roger. I wish the pics worked on that page. I have about every manual except for the factory one (Haynes, Bentley, Chilton). I don't think they had a good step by step in any of those as most people say to replace it.

 

check the pirate4x4 forum, the FAQ there has links to some detailed write ups on rebuilding the IFS steering box, its not to extreme.

I have a pdf copy of a scanned '85 repair manual ( 57mb ) but it has the '85 box in it. =/

probably similar rebuilds though

 

I'll be following this thread..mine is on it's last legs.. been leaking for a long time and been steadily getting worse. The other day it was whining everytime I turned the wheel until it warmed up. It's time to rebuild her.

 

That's probably the power steering pump rather than the box.

I'll cruise around pirate and see what I can find. If I find some good info I will post it up here. Also, I think I have found a used box and I'm still going to rebuild it and then swap it out and keep my old one as a spare.

 

So did you ever rebuild your steering box? I have the seal replacement kit from toyotapartsales.com, but looking in the FSM that I have (purchased in 1989), it looks like you need some SST's to rebuild it. Any hints?

 

Pictures on that page work fine. Just give them time to load.

Here are some:

 

You can buy rebuilt hopped up ones from PSC and send them your old one for $250.

 

Any hints on how to go through it completely w/o spending hundreds on SSTs?

Does anyone know how to get off the nut on the end of the shaft that requires a odd large wrench?

BTW, The FSM link that 4Crawler listed above is dead...

 

I'm not sure how much your time and safety is worth to you but a new/rebuilt one with a core charge is about 350-500 bucks... they won't leak PERIOD. Also like brakes you might want to consider leaving vital steering components to a profesional.

 

I've never needed an SST for anything, and as far as most people would say, I've completely "remanufactured" my 88 pickup. There's always a way to make one or use a different tool/method entirely. From browsing through the FSM(Here's a link to the 93 FSM: http://personal.utulsa.edu/~nathan-b...ng/13gearh.pdf) it looks like instead you could use line or socket/crescent wrenches for a couple of the hydraulic fittings, a brass drift pin and a hammer(or a slide hammer/seal puller)to knock out the cross shaft bearings from the housing, and a pair of pliers with protected jaws for the worm gear removal. And FYI, a block of wood or the right size socket installs seals just as good as any SST "seal installer". I'll bet ya a $100 I can rebuild one without using 1 SST. Mines not leaking that bad yet, but I need the money, so let me know.....

The large nut that holds the pitman arm to the cross shaft requires a 32mm socket, 1&1/4" socket is equivalent. And a gear puller or the hammer and drift method will remove the pitman arm from the cross shaft easily, sans SST.

 

The SST that I'm most concerned about is the 09631-00030 & 09631-00040 combination that are used to take off and put on the lock nut on the adjusting screw that is on the worm gear shaft. Sounds like a bottom-bracket wrench for bicycles might work for that...

 

Bumping this one back to the future... 4crawler, how the heck did you undo the stakes on the plate that holds the input shaft UP to the housing, I can tell it's aluminum but i can get anything small enough to hit it with enough force to bend them back.

 

Sorry, have never torn one apart before.
