How to install Wheel-Check® properly

1. Torque wheel nuts to proper specifications (recommended ft/lb).
   
2. Ensure correct size by measuring unit from flat to flat (diagram 1),
   
3. Place one Wheel-Check® over each nut with the raised collar towards the wheel. Wheel-Check® name, number and size should be facing out. Hold the arrow of the indicator pointing in your preferred pattern. Push the Wheel-Checks on with a socket wrench or a PVC pipe. It’s that easy, no other tools required.* (diagram 2).
   
4. For disc wheel, point the point to the center following stud (photo 1).
   
5. For other wheel types (spoke pattern), point indicators towards the hub (photos 2 and 3).
   
   * STEP #3 IS VERY IMPORTANT FOR CORRECT INSTALLATION.

THE DRIVER WILL DO THEIR WALK-AROUNDS BY LAW. If a nut has backed off as little as 50 ft-lb, the driver can notice if he observes closely. Once the nut has backed off 100 ft-lb, the movement is easily noticeable.

INSTALLATION OF RED WHEEL-TORQUES. If the driver notices a nut has moved, the driver would remove the yellow Wheel-Check®, retorque the loose nut and then replace with a red Wheel-Torque. This would identify the loose nut to the maintenance shop at a simple glance and they will know that the whole wheel must be carefully serviced.

Wheel-Check® is an indicator and must always be visually checked when a driver is leaving or getting into his truck. Please call 888-829-1556 with any questions or concerns.
