Wheel Lug Nuts/Wheel Liners
Torque is the amount of rotating force applied to a lug nut, and can only be achieved by using
a properly calibrated torque wrench and socket.
Do not use a 4-way socket or any other type
of wrench that does not measure the actual pressure applied to the lug nut.
™
NOTE: The proper method of tightening wheel lug nuts is with a torque
wrench, not with an impact wrench or by hand. 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.
After your first trip, check the wheel lug torque periodically for safety according to your
Chassis Guide. If you suspect the wheel lug nuts have loosened at any time, have them
checked and torqued to the proper limits immediately.
Lugs should be checked:

After winter storage

After a wheel removal

Before starting a trip

Following extensive braking.
 Check and re-torque after the first 10, 25 and 50 miles (16, 40 and 80 kilo-
meters). Thereafter, check and maintain the torque according to the listed
torque values.
Refer to the Chassis Guide for torque guidelines.
Wheel Lugs
If you suspect or notice the wheel stud bolts are cracked or broken, they must be replaced,
along with adjacent bolts that have probably also been weakened due to the additional stress
placed on them.
Aluminum Wheels (if so equipped)
Clean the aluminum wheels with a cleaner that is designed for use on aluminum and apply
an appropriate protection agent. Do not use abrasive cleaners. Wheels exposed to sea water
or road chemicals should be cleaned as soon as possible. Be sure to use a sponge or chamois
leather (brushes may damage the aluminum wheel surface).
™
NOTE: If your motor home is equipped with aluminum wheels, only the
outer dual wheels are aluminum, the inner duals are steel wheels.

Check and tighten the wheel lug nuts regularly to ensure they did not
loosen during travel. Refer to your Chassis Guide for torque recommen-
dations.

Failure to tighten and maintain wheel lug nuts to the proper torque speci-
fication, could allow the wheels to come off while driving, resulting in
serious injury or property damage in the event of a collision or loss of
vehicle control.
Tires
Read and understand the following before taking your first trip in your RV.
Routine maintenance on your RV is important.
To ensure your tires are operating safely,
regular inspection of the tires and checking tire pressures is absolutely mandatory.
