How do you get the steering box on a 72 Chevelle to stop squealing?

To stop the steering box on a 1972 Chevelle from squealing, first check the Power Steering fluid level and top it off if necessary, as low fluid can cause noise. If the fluid level is adequate, inspect the steering box for any leaks or damage. You may also need to adjust the steering box's preload screw, but do this carefully to avoid over-tightening. If the squealing persists, consider replacing the steering box or consulting a professional mechanic.
