I'm not real savvy on the early steering boxes but it sounds like a problem with the clearances between the sector gears (Pittman shaft).
First order of business is the verify the adjustment - Below are the instructions from the dealer shop manual.
Rotate the left housing counterclockwise (as viewed from the left side of the tractor) to eliminate backlash.
Secure the sector shaft bearing housing by installing the washer and four cap screws. The adjustment between the left sector and ball nut should be such that a pull of 2 to 3 pounds is required to turn the steering wheel through the straight ahead position.
Place the right sector shaft and thrust washer in the sector shaft bearing housing, and position the metal gasket on the housing. The right sector must be engaged with its center tooth meshed in the third tooth space on the left sector gear, counting from the solid section of the gear, located on the bottom. The tooth on the right sector can be identified by a dot or mark on the end of the tooth.
The tooth space on the left sector also can be identified by a dot or mark. The bearing is eccentric in the sector shaft bearing housing and should be installed with the notch located at the bottom. Rotate the housing clockwise (as viewed from the right side of the tractor) to reduce backlash.
The adjustment between the right and left sector should be such that the force required to turn the steering wheel through the straight ahead position is 3 to 6 pounds.
I'm sure one of the experts will be along shortly with better advise.
