Chevrolet 1-Ton Steering & Hydroboost Brake Rebuild - Stop Steering At My Secrets
|
There are both variable-ratio steering boxes and single-ratio steering boxes. The boxes use different pistons and sector shafts. The piston on the left is variable ratio such that as you turn farther to one direction the steering quickens. In high-speed driving slight steering-wheel movement doesn't have a quick reaction in the wheels off center, but when slow steering such as in a parking lot you can quickly point the tires as you get farther from center. The straight-cut piston (right) keeps the same ratio throughout the entire turning cycle and can be twitchy, slow, or just right depending on what ratio is used and what speed the vehicle is traveling.
