WHEEL LUG TORQUE CHART
Wheel Lug Nut Diagrams:
Wheel Torque Instructions: * All torque wrenches mentioned below must have settings visible for auditing purposes.
1. Start lug nuts with fingers on studs to avoid cross threading.
2. Stage 1, Torque
: Impact lug nuts in a star pattern* until snug to rim. -- See Wheel Lug Nut Diagram
3. Stage 2, Torque
: Use calibrated torque wrench to torque each lug nut, in a star pattern, to the values indicated.
Wheels must remain stationary during torquing process for control purposes. --
See Wheel Lug Nut Torque Chart and
Wheel Lug Nut Diagram
4. Stage 3, Torque: Use calibrated torque wrench to torque each lug nut, in a star pattern, to the values indicated.
Wheels must remain stationary during torquing process for control purposes. --
See Wheel Lug Nut Torque Chart and
Wheel Lug Nut Diagram
5. Confirmation Torque checks
: Every 10th unit produced must be verified for torque using a calibrated torque wrench

Transportation Instructions:
1. Prior to travel and after excessive braking, all wheel lug nuts must be checked for torque.
*This also applies to any service involving wheel or lug removal, during the life of the recreational vehicle.
2. Torque readings must fall within the Acceptable Torque Range. --See Wheel Lug Nut Torque Chart
3. Torque specifications, must be checked by using a torque wrench.
*
Digital or Dial Torque Wrenches are recommended
4. If Torque falls below the Acceptable Torque Range, additional torque is required.
--
See Wheel Torque Instructions and Wheel Lug Nut Diagram for the correct pattern and recommended final torque value.
5. During travel, wheel lug nuts must be checked and re-torqued, as required, after the first, 10 miles, 25 miles, 50
miles, then periodically during travel (16 kilometers, 40 kilometers, 80 kilometers, then periodically during travel).
-- See Wheel Torque Instructions and Wheel Lug Nut Diagram for the correct pattern and recommended final torque value.
6. Failure to follow these instructions may result in wheel loss, an accident, or loss of control, resulting in death or
serious injury.
