What is the role of a torque wrench during suspension repairs?

A torque wrench plays a crucial role in ensuring proper nut tightening during suspension repairs. When working on suspension components, it is vital to tighten fasteners to the manufacturer's specified torque settings. This is important because over-tightening can lead to component damage or failure, while under-tightening can result in loose components that might lead to unsafe vehicle handling.

Using a torque wrench allows the technician to apply a specific amount of torque to the fasteners consistently, which helps maintain the integrity and performance of the suspension system. Properly torqued components reduce the likelihood of issues such as fatigue failure and excessive play in joints, ultimately enhancing the safety and reliability of the vehicle.

The other options, while related to vehicle maintenance, do not describe the specific function of a torque wrench in suspension repairs. Applying force uniformly, adjusting wheel alignment, and checking air suspension levels are important tasks in their own right, but they do not specifically pertain to the role of a torque wrench in ensuring that nuts and bolts are tightened correctly.
