Which of the following could indicate a steering defect?

• A. Worn tires.
• B. Engine misfire.
• C. Excessive play in the steering wheel.
• D. Brake pedal squeal.

Answer: (C)

Excessive play in the steering wheel signals a problem in the steering system. When there’s too much free movement before the wheels begin to turn, it means some component in the steering linkage or its mounts is worn or loose—such as track rod ends, the steering rack, or related joints. This looseness makes the steering feel imprecise and can cause delayed or unpredictable responses, which is a serious safety risk for a large vehicle. In LGVs, where precise, predictable steering is crucial, any noticeable play should be treated as a steering defect and checked promptly.

Worn tires can cause wandering or uneven handling but aren’t a steering defect. An engine misfire affects engine performance, not the steering mechanism. Brake pedal squeal relates to the braking system, not steering.
