Methods and apparatus for testing automotive and truck wheels and hubs include placing a wheel connected to a hub and an arm or axle like member into a frame which maintains the wheel relatively fixed. Actuators are provided to apply forces to the wheel through the axle and hub. The forces are applied in different directions with the actuators being programmed to simulate actual road conditions over a long period of time in a relatively short test time without requiring substantial rotation of the wheel.
