ASE Suspension and Steering (T5) 2025 – 400 Free Practice Questions to Pass the Exam

Self-steering lift axles are designed primarily to enhance truck maneuverability. These axles allow the vehicle to navigate tighter turns more easily by turning slightly in the direction of the front wheels, effectively reducing the turning radius. This feature is especially beneficial in larger vehicles, such as trucks and trailers, which can otherwise struggle with tight cornering due to the length and weight of their configurations.

In contrast, the other options do not accurately describe the primary function of self-steering lift axles. They do not inherently increase truck speed; their purpose is more closely aligned with control and turning ability. While they do contribute somewhat to load distribution and stability, they do not add additional braking force, as that is typically managed by the braking system. They are also not limited to supporting static loads; self-steering lift axles effectively support dynamic loads while in motion. Thus, enhancing maneuverability stands out as the correct and relevant function of self-steering lift axles.
