I just looked this up online and found a pretty good website. Although I havnt tried to do it yet on my own corvette I probably will within the hour http://www.diynetwork.com/diy/ar_1962_corvette/article/0,,DIY_13704_2278440,00.HTML this is the URL as well as some of the directions from the site
the next step in this restoration is to adjust the Corvette's steering using the steering-box located underneath the hood. An earlier test-drive revealed that the steering wheel exhibited some play during driving. Since the other steering components have been checked and found to be in good shape, the play may be due to wear in the gears inside the steering box.
The Corvette's steering box permits adjustment of these gears, which may well solve the steering problem. Adjustment of the steering requires two people, but the job can be done in just a few minutes.
If the gearbox is causing freeplay in the steering wheel, then the gearbox needs to be replaced.
Bad coupling from the steering wheel to the rack & pinion or steering gear. Faulty steering gear
To adjust the steering gear box on a 2002 Tahoe, first, ensure the vehicle is on a level surface and the steering wheel is centered. Locate the adjustment screw on the top of the gear box and use a torque wrench to make slight adjustments—typically no more than a quarter turn at a time. After each adjustment, test the steering feel by turning the wheel and checking for play. Repeat as necessary until the desired steering response is achieved without excessive tightness.
To convert the rotational movement of the steering wheel, into linear movement at the wheel.
u cant make sure wheel bearings and all other suspition is tight
It could be worn tie rod ends, if not then you need to check the steering box. The worm gear could be worn and you can adjust it with the nut on the steering box.
Steering boxes can be tricky to adjust. Takeit to a garage or dealer.
You have to adjust the tie rods ends between the steering arm and the power steering gear, just make sure your wheels are set straight ahead, and that you don't have any alignment problems. If you don't want to do this on your own take the Blazer to your nearest alignment center and have them center your steering wheel.
You should NEVER have to adjust a new gear box. You have other front end problems that are worn out.
The five general components of a steering system are the steering wheel, steering column, steering gear, linkages, and the wheels themselves. The steering wheel allows the driver to input direction, which is transmitted through the steering column to the steering gear, converting rotational motion into linear motion. The linkages connect the steering gear to the wheels, ensuring that turning the wheel effectively pivots the wheels in the desired direction. Together, these components enable precise control and maneuverability of the vehicle.

To adjust the steering gear box on a 1999 Ford F-250 4x4, first, ensure the vehicle is on a level surface and the front wheels are straight. Locate the adjustment screw on the top of the steering gear box, then use a wrench to turn it clockwise to tighten or counterclockwise to loosen, making small adjustments until you achieve the desired steering feel. After adjustments, check for play by turning the steering wheel and ensure there are no binding or excessive tightness. Finally, recheck alignment and test drive to confirm the improvement.
