Josam's Wheel Alignment Station JT 4000 received a software upgrade for its Bluetooth measuring heads and computer program. The wireless heads are faster and can now take measurements in less than one second. Techs can now track the battery life remaining for each specific sensor. The guided flow in the process has been updated to take into account up to six steer axles per vehicle and a total of 18 axles. Steer axles can now be measured in about one minute and non-steer axles in less than 10 seconds.
