Steering Gearbox Ball Bearings
« on: November 01, 2017, 01:35:36 PM »
Has anyone replaced the free floating ball bearings in their steering box?   Am looking for info on the size and possible source(s) for these bearings.
Thanks for any info,
Kurt.

I recall seeing the diameter somewhere, probably in VMF assuming you searched here and did not find.  If my memory is good the conclusion was that it is not readily available in the size and the best source was from the donor ranks.  There are a lot of donors out there so you might want to post a wanted ad with quantity needed.

 I went over and found the information posted, which is attributed to Chockostang:  There are 62 balls with a 0.230" diameter.   There were quite a few posts looking for a place to purchase them but there were no answers...other than donors.

Thanks for the reply - I read same VMF thread.  Too bad its an odd size.   
I was preplanning a box rebuild and am not sure I will need new brgs but wanted to be prepared in case.  The box is still in car and seems to work OK just a little loose and leaky lower seal.  Hope I will not need any brgs.

Step #1 don't lose any ;)  No need to ask me how I know.  Funny how they end up rolling into the hardest to find places.

Any of the mustang parts places sell a steering box rebuild kit which comes with the ball bearings, needle bearings and seals.  I've used the kit maybe 5-10 times with no issues.

NOS bearings can be found, but will be a bit of work to hunt down and will end up being about 3-4X the cost of the repro parts.

Back when rebuild kits were not so easily sourced parts maybe 25 ,30 years ago we had to improvise. The bearings you could find but the ball bearings were harder to find. We would take all of the balls out ,clean and after inspecting the ball bearings for cracks abrasions etc. put all the good ones back.  Any damaged balls were replaced using a donor box for parts. We would typically have to add balls to the total count to compensate for wear and tighten clearances up.

I see the sizes are all slightly over 0.230".   It would make sense to use slightly oversize to tighten slightly worn box, but how much oversize without binding?    Do you have any recollection of exact size you used, and if you noted any binding, etc.?  I also presume chrome steel means the chrome is added to the steel and not plated.
Thanks for the info and link,
Kurt.

I asked Dan the same question. His reply was as close to .230 as possible. Didn't discuss oversize to account for wear.
Not chrome plated as you presumed.No binding.Nice guy. Wouldn't be afraid to call him for guidance.
