Need a quick answer... Toyota PS Box

[Dave]

How well do the Toyota power steering boxes work on the Bronco? It is the correct one... I've only got a few hours to pull it. Thanks...

I think it is the same or very similar to the Nissan box.

Here is a thread on it over at bfix.:

It has been on my list as one of those things to try for a few years. How much? If free get it. Nothing but 30 mins. lost.

I looked at that some time ago and have been keeping my eyes out for one. Mostly interested about the ratio and if they are heavy enough for the application. How well they work with an Explorer pump etc.

 

[broncodriver99]

One thing I have heard is that they like to break the casting like stock boxes if used hard on anything over 33" tires.

i understand they are a great ratio for offroad but on the road they are a bit quick..not sure how they hold up

I've been running one ('90 4-runner) for over a year now, and love it on the hiway, makes my old rig drive like a new car. Not too quick of a ratio for the hiway at all. Only running 31's and don't off road to severely, so no problems there. I think NVRSTK runs one also, and he running 35's at least and thrashes it.... and he's not complaining.

The 1986+ IFS Toyota boxes have been a favorite in various off-road communities for a while...most of the high-steer solid axle Toyota guys swap to the IFS box without issues, many of which are running 35-42 inch tires and beating the piss out of them with similar weight rigs (3500-4500#). Easy to port for ram assist which is probably the best thing you can do to take some load off of the box and sector shaft IMO.

Went and pulled it this morning. It came off a 86 Toyota pickup IFS. Its considerably smaller and lighter than the 4X4X2 converted box I was planning on using. I can stay with plan A and give the Toyota Setup to my brother for his 73. Use it and give him the big box. Or upgrade my 85 Yota to high steer. The 4X4X2 box has a little sector gear wear and this one is like new. Very smooth and 0 back lash stop to stop.

It looks like a great fit. Looks like the one frame hole would postition it nicely and the other 2 will be in the frame rail.

What are guys using for a pittman arm?

 

[DirtDonk]

What kind of wear? Are the splines twisted? That's pretty common on older ones that have been in accidents. Even those that have not been crashed hard can have some twist to the shaft, so it's one of those things we look out for when choosing a 4x4x2 core.

Good luck.

I think its just some normal wear. The box was out of a 78 Bronco and the rack/screw was out of an Econoline van. If you adjust the backlash out in the center it gets a little thight at the stops. probably just a little mismatch between two slightly worn components.

Did your Ford lower shaft fit on the Toyota splines?

That's the Toyota arm on the box. Have not pulled it yet. Toyota uses a ball joint in the arm and a tapered hole in the tie rod. I could fab up a tie rod with a tapered hole on the steering box end and a hiem on the other end.

Ouch! $135 for a pitman arm for my $25 PB box. Thanks for the link if I need it.

 

[rjrobin2002]

Use the stock pitman arm and change the taper or drill it for a hiem.

The ball joint is part of the Toytoa arm. I'm thinking of making a drag link with with a tapered hole in the upper end. It might work better at keeping water out.

It might be possible to pop that ball out and machine it for a heim.

I see, I thought you were refering to the Toyota steering shaft had a ball joint. I bet you could pull it apart and get a 7/8" hole drilled. I may have an old Toyota arm from a lift I installed years ago in my shop off a 93 4x4 I can tear apart to measure if there is enough material. That way you will not have to break your good one.

Thanks! That would be helpfull.

Bad news, looks like the pitman arm I had is missing. I read somewhere else that they just cut them in half and welded a ford end on the Toyota arm. I am not sure what material those arms are made of, but I think it is forged steel.
