What should be checked to ensure the steering linkage is in good condition?

To ensure the steering linkage is in good condition, it's crucial to check for wear or cracks in connecting links, arms, and rods. The steering linkage is responsible for transmitting the driver's input to the wheels, allowing for proper steering control. Any wear or cracks in these components can compromise the safety and functionality of a vehicle's steering system, leading to erratic handling or failures.

By inspecting these parts, a driver can identify potential issues before they lead to a more serious problem. Regular checks help maintain the integrity of the vehicle's steering and ensure a safer driving experience. The other options pertain to cosmetic aspects or unrelated functionalities of the vehicle, which do not directly affect the condition of the steering linkage.
