Anyone else had problems with steering boxes? In the last 3 years or so, ive been thru 4 Boxes. Original started leaking, put on a used one that lasted no time before it started leaking. Ive put on a new one, that lasted no time, replaced it and now this one is leaking. Anyone else have problems with these?

 

I think you can rebuild the steering box can't you? Maybe it's time to go that route instead of replacement?

 

I resealed mine, and other than taking the spiral gear out(which the manual told me not to do) and having the individual ball bearings roll everywhere, it was pretty straight-forward.
Under most cases I've found it better to rebuild the genuine Toyota component whenever possible rather than get a aftermarket one. And a used one will typically have the same issues as the one you're replacing.(or worse)

 

kind of like building a castle upon a sunken castle upon a sunken castle.

 

Ar you using power steering fluid or automatic transmission fluid?

 

*this

While hydraulic fluid is always hydraulic fluid there are known issues with seal and metal issues.

 

X2 on this.

I just bought a 88 pickup and found the last owner was not using ATF. The oil seemed thicker than power steering fluid but whatever it was I flushed the system out and replaced it with Mobil1 ATF, hopefully it didn’t destroy any of the seals, but time will tell!

 

Ive been using power steering fluid.

 

Drain the system, put a new box in or new seals, then flush the system with ATF (Dex-II/III I believe is the most correct) I used Mobil1 Synthetic ATF.

 

Correct^^^.
