    As suggested, the input is backwards. I took the gear off and reversed it. So how do the ball bearings go back in without jamming them up in the housing?

    Rotate the input shaft as you feed in the bearings.

    35joe, when you pull the top off the box, don’t pull the out put shaft with it. Unscrew the adjustment screw , leaving the output shaft meshed with the input gear. Then turn the input and observe if the output shaft turns the same distance both ways.

    When you assemble the steering box, you need to be sure the input “ gear” is in the center of its travel, when you drop the output shaft into the housing/ input gear. If it is not “ centered” it can be a tooth or more off.... out of “ time” causing it to not turn all the way one way. Thus, reducing the number of total turns of the steering wheel.


    When you turn the input shaft all the way one , there should be no teeth left on the out put shaft, either way!

    I’ve got 6 input turns resulting in 1/4 turn for the pitman. Is that correct?

    If you now have 6 full turns of input, and not the 2 1/2 you started with, that part is good. Now center the input and go three turns both ways from center. If the pitman arm moves the same distance in both directions, you have the worm and sector centered.

    The set screw is set using a torque wrench on the input shaft to monitor how much drag you introduce when turning the screw. Look up the spec to be certain. The specs should list two values. One is for setting the input shaft preload when installing the threaded end cap. The second is the lash load. As an example, the GM 525 box wants 5 to 8 inch pounds needed to rotate the input shaft. That's with just the input in the box. Then for the center lash adjustment, you rotate the input a little bit either side of center while screwing in the screw. To check your adjustment, rotate the input with the torque wrench and watch how much extra effort is needed as you cross center. The GM spec is 14 to 16 inch pounds. That's by the book. You can also just do it by feel. You just want enough extra drag at the center point so the car won't wander. Same with the input preload. Take the end play out and just a little snug to preload the bearings. Just recheck after tightening the lock ring.
