Light Front, Runs and Drives, Airbags Good., , What motorists are now learning is that car-based SUVs are in many ways superior to truck-based types, especially in the areas of ride and handling. The reasons are simple: One is that car-based trucks feature four-wheel-independent suspension where the truck-based variety usually has a solid rear axle, which compromises both ride and handling. This type of suspension, and the ground clearance considered necessary in a work truck, also tend to raise the vehicles center of gravity and its rollover propensity. Finally, body-on-frame trucks may be strong, but theyre typically not rigid. They shudder and twist. Aside from inducing squeaks and rattles and generally lowering ones perception of the vehicles quality, this flexing makes the suspension components wonder where the heck they are and to give up on the task of holding the wheels to the road.
