Wheel Lug Nut Torque Values
1. Prior to travel and after excessive braking, wheel lug nuts should be checked for torque.
Torque readings must fall within the Final Torque Values in chart above.
2.
Torque specifications should be checked using a proper torque wrench.
3. If the torque falls below the Final Torque Values, additional torque is required.
4. Check and re-torque lug nuts at 10 miles (16 Km), 25 miles (40 Km) and 50 miles (80
Km) and again periodically during travel. Refer to diagrams above for proper lug pat-
tern and Final Torque Values. Thereafter check and maintain torque according to the
Final Torque Values in the chart above.
Failure to follow these instructions may result in wheel loss, an accident, or loss of con-
trol, resulting in death or serious injury.
Lug Nut Pattern and Warning Label
The following labels showing the proper lug nut tightening pattern and a warning label are
located on the driver side of the A frame hitch on travel trailers, and on the driver side of the
pinbox on fifth wheel units. Lug pattern label will vary according to number of wheel lugs.
Torque Wrench Usage:
1. Tools should be maintained, in good condition, and stored appropriately.
•
Avoid dropping or sliding a torque wrench. Dropping it can cause the instrument
to lose reliable calibration.
