Underloaded front axles can lead to too much play in the steering wheel and poor traction for several reasons. When the front axle is underloaded, it does not have sufficient weight pressing down on it. This can cause the front tires to make less contact with the road, which diminishes grip and responsiveness.

The steering system relies on the tires having a firm connection with the surface to provide accurate feedback. If there is insufficient weight, the driver may feel excessive movement or "play" in the steering wheel, leading to a lack of control when maneuvering. Additionally, poor traction can be particularly problematic in various driving conditions, such as wet or icy roads, where optimal contact with the road surface is crucial for safe handling and stopping.

In contrast, excessive fuel consumption relates more to engine performance and load, increased stopping distance typically involves factors like vehicle weight and braking efficiency, while overheating of the engine is more directly tied to engine function rather than axle load. Thus, too much play in the steering wheel and poor traction is the most directly connected outcome of underloaded front axles.
