Two technicians are explaining how to replace a VGT (variable-geometry turbocharger) actuator. Technician A says that you hold and shake the sector gear inside the turbocharger to check for excessive movement, which would indicate a failed bearing in the sector shaft. Technician B says that if the sector gear does not sweep freely, the turbocharger will need to be replaced. Who is right?
