When installing a tandem drive axle truck on a chassis dynamometer, it is essential to ensure safety and stability. The front axle wheels must be wedged and chained to prevent the vehicle from moving forward or backward during the testing process. This is because the dynamometer applies force to the drive axles, potentially causing the vehicle to shift if not properly secured. The drive axles themselves are engaged with the dynamometer and thus are not wedged and chained.
