Personal injury and damage may result from high speed spinning. Important: This step will require the assistance of another person to maintain the drive train speed. Do not use the cruise control to maintain the drivetrain speed. Important: Do not allow the stethoscope to contact any moving components. Does either wheel bearing exhibit noise? | -- | ||
