ASE Suspension and Steering (T5) Practice Test

Slightly positive camber is often the typical alignment for trucks with respect to the front wheels. This alignment helps in optimizing tire contact with the road, enhancing stability, and providing a better load-carrying capability. When trucks are loaded, having a slight positive camber allows for the body of the truck to settle somewhat, maintaining proper tire contact during operation. This is particularly important for vehicles that frequently carry heavy loads, as it aids in distributing the weight evenly across the tires and helps improve handling characteristics.

In contrast, other options suggest either no adjustment or varying degrees of camber that do not meet the needs of truck performance or load handling. A slightly negative camber could lead to increased wear on the tire's inner edge and may not support heavy loads adequately, while having exactly zero camber or no specific camber at all could lead to compromised stability, especially during turns or when traversing uneven surfaces. Hence, the need for a slightly positive camber directly addresses the operational requirements of trucks under varying load conditions.
