SECTION 4 TOWING & SET-UP
Check and re-torque after the first 10, 25 and 50 miles (16, 40 and 80
kilometers). Thereafter, check and maintain the torque according to the
listed torque values (see Wheel Lug Torque Chart.)
 NOTE: The proper method of tightening wheel lug nuts is with a properly
calibrated torque wrench and socket, not with an impact wrench or by hand. Do
not use a 4-way lug wrench or any other type of wrench that does not measure the
actual pressure applied to the lug nut.
Because of the importance of having proper torque on the wheel lug nuts, you
should always have the wheels mounted and properly torqued by a qualified
technician using the proper tools.
Check and tighten wheel lug nuts regularly to make sure they did not loosen
during travel. Wheel lug nuts must be applied and maintained at the proper
torque levels to prevent loose wheels, broken studs and possible separation
of the wheel(s) from your trailer. The lug nuts on the wheels of your RV must
be maintained according to listed torque values (see Wheel Lug Torque
Chart.) Over-torqued and/or under-torqued wheels may result in component
failure.
