Manual Steering Box...assistance needed...

They are very easy to “rebuild”.
The ball bearings in the top and bottom and needle bearings on the sector shaft are rarely bad.
Just take it apart, good cleaning, pack with new grease.
I do not take the ball assembly apart. The manual does not say to.
I just clean it out with mineral spirits and compressed air.
Only need two seals.
Chicago Rawhide 11067 and National 7214.
Later tonight when I get home to another computer, I think I have some pics. of one I just did.
The service manual has instructions.
If you want I can scan and upload that too.
The biggest thing is DO NOT loose the needle bearings in the old grease.
Be very careful.
I count them on removal and keep up with them.
You can do it for a few bucks.
Not much of an adjustment to it when you get it back together.
You can guess at "inch pounds".
