Which of the following is part of the suspension components?

The correct choice highlights U-bolts as an essential part of the suspension components in a vehicle. U-bolts are curved bolts shaped like the letter “U” and are typically used to secure the axle to the suspension leaf springs. They are designed to bear the weight of the vehicle and maintain the proper alignment of the axle with the frame, playing a critical role in suspension integrity and vehicle stability.

When conducting a pre-trip inspection, it’s crucial to ensure that U-bolts are not damaged, rusted, or loose, as these conditions could lead to suspension failure, affecting the vehicle's handling and safety. Thus, recognizing U-bolts as part of the suspension system demonstrates an understanding of how different components work together to keep the vehicle functioning safely.

In contrast, the drag link is part of the steering mechanism, the power steering reservoir is related to the steering system, and gear-driven components pertain to drivetrain mechanics rather than the suspension system. Understanding these distinctions is key in identifying components during a pre-trip inspection and ensures that the vehicle operates efficiently and safely.
