Steering Box Sector Shaft Loosening Itself
« on: Jun 16, 2018, 11:27:59 PM »
Hey guys, I've been fighting with the steering box over the last few months and hoping somewhere here might have some ideas for me.

The basic issue I'm having is that every time I go out wheeling lately I have had an issue with the Sector shaft bolt on my steering box backing itself out and then leaking / dumping all my fluid. I'm on my 3rd remanufactured box now with all 3 of them doing the same thing while wheeling.

I am capable of rebuilding the box9es) myself, but my concern it will just keep happening (and cutting my wheeling trips short) if I don't understand what is causing it.

The only thing I can currently think of is that with 35's and a stock pump / IFS box, the steering often can't handle the load. When that happens I just force the steering manually through the wheel. I've wheeled other Toyotas in the past in the same way and never had this kind of issue, but I've also never had the size tires, lift, etc. I have on this one, nor have I tried trails at the level I am taking on now.

The only thing I can think of to help is to add a Hydraulic ram so the stock box isn't working as hard, but again I'm concerned that without finding the true root cause it will still keep happening.

Any suggestions are greatly appreciated!

There is no reason gor the bolt to back out.  It isnt evem doing anything except touching the top of the secotor shaft. 
My recommendation is get a known good used box and quit freakin' with reman garbage.
hold this. . .

Any recommendations on how to identify a "known good used box", seems like that would be just as problematic as buying a new or remanufactured unit.

The first box that failed was actually a used unit that worked fine for me for well over a year, but I never did any heavy wheeling with it. I discounted this because it was a used junkyard unit of unknown origin.

If it's the bolt I think it is....  (the one on top in the middle)  they have a jam nut.

A  ... "known good used box", seems like an oxymoron?

Yep, jam nut has been there every time, torqued and adjusted properly. Its fine right up until I take it out wheeling and then it appears to self loosen.

Im going to try re-adjusting my current box and then seeing if theres anything I can do to lock it down better.

First box was known good. Worked great for 2 years, right up until the first time I took it off roading (beyond basic suspension flex tests at least).

Since it appears Im the only one to have ever experienced this problem, looks like Im just going to have to analyze my setup one piece at a time and see if I can figure out why its backing out.

Thanks everyone!

Random thought. Did you move your steering box forward? Is the nut resting on the inner fender or core support somehow and vibrations/movement is causing the top bolt to loosen up?

Good suggestion. I'm pretty sure I have a solid inch of clearance between the spring and the pitman arm at full compression, but I'll have to confirm.

It's actually an '85, so I had to fab in the box. It is moved pretty far forward, but I cleared out all the metal around it. There is a minimum of a 1/2" clearance all around the box. Several inches above the top of the steering box / sector shaft nut / bolt.

Put something like this:

on the jam nut and safety wire it so the jam nut can't turn.
