Author Topic: steering box teardown (Read 281 times)

My car had not driven in the 20 years before I got it, so I decided to go thru the steering box. It is a std 19:1 box, but I am adding quick turn pitman and idler arms to improve performance. Anyone have this combo? Wondering how it will be, as the quick turns are usually used on 16:1 boxes I think…

Box as removed (broken, seized up bolt and all):

Pull off Pitman arm w/ Autozone rental puller:

Remove cover plate and sector gear:

Sector Gear:

Remove the big sheetmetal locking nut and remove shaft and ball nut:

Address the broken bolt, center punch, drill... got lucky, was almost up to the tap drill size when it grabbed and turned the remaining threads of the broken bolt out:

Everything looked good, so I decided to just clean out all the grease, replace the seal and re-assemble and adjust:

Reinstall the shaft, supposed to tighten to pre-load the bearings and produce a shaft running torque of 4-5 in-lbs after the lock nut is tight:

Check the sector shaft shim clearance, should be .002”:

Put the sector gear back in with the adjusting screw, gasket and cover in place. Adjust the screw until the steering shaft running torque increases to 9-10 in-lbs at the center of its motion. These boxes are designed to drag at the center to ride better on the highway.

Pump it full O’ grease, paint, and a quick turn pitman arm and it hopefully ready for another 45 years of operation…

Very nice write-up. This comes at a good time for me. I need to tear into my steering box because I have too much play in the steering shaft itself. I have a guy who is giving me his old box that he replaced and I was going to practice on that box first but your write-up helped me out with questions about the internals of the box. Good job. :10

Nice work and nice write up, where do I send my box? :)
j/k Stanger did mine this year, can't wait to test it.

I looked through http://www.stangerssite.com quite a bit prior to starting, he has some adjustment procedures and lube info and also what to look for for wear/damage, I would recommend it to anyone thinking about rebuilding...

I got lucky, my internals were perfect, nothing needed to be replaced...

very good write up, you should put it in the "tech articles" section so we can find it again when we need it. It's a great reference. Thanks for posting it.
