Passive four-wheel steering systems use __ that allow a limited amount of rear-whe el steering, typically toward the inside of the corner, under cornering maneuvers. a. Actuators b. Steering linkages c. Steering knuckles d. Compliant rubber bushings

## Step 1<br />The problem is asking us to identify the component in passive four-wheel steering systems that allows a limited amount of rear-wheel steering, typically toward the inside of the corner, under cornering maneuvers. <br /><br />## Step 2<br />The options provided are: a. Actuators, b. Steering linkages, c. Steering knuckles, and d. Compliant rubber bushings.<br /><br />## Step 3<br />We need to understand the role of each component in the context of a four-wheel steering system. <br /><br />## Step 4<br />Actuators are devices that move or control a mechanism or system. They are not typically associated with the steering system.<br /><br />## Step 5<br />Steering linkages are the parts of the steering system that connect the steering wheel to the wheels. They are not typically associated with the steering system.<br /><br />## Step 6<br />Steering knuckles are the parts of the steering system that connect the wheels to the steering system. They are not typically associated with the steering system.<br /><br />## Step 7<br />Compliant rubber bushings are flexible components that allow for some degree of movement. They are typically used in passive four-wheel steering systems to allow a limited amount of rear-wheel steering.
