Section 4: Vehicle Operation
After this road test has been completed, front-end alignment and/or vibrations will not be
covered as part of the new vehicle limited warranty.
Follow the Chassis Guide maintenance instructions for the front and rear axle for wheel and
suspension maintenance, including the brakes and wheel bearings. Contact your Chassis
manufacturer for assistance.
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.
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 or
following extensive braking. Refer to the Wheel Lug Torque Chart.
 Check and tighten the wheel lug nuts regularly to make sure they
did not loosen during travel. Refer to your Chassis Guide for torque
recommendations.
 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.
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.
NOTE: Always have the alignment checked and adjusted by a qualified
shop with the proper equipment to handle heavy vehicles.
NOTE: A road test by the dealer should be included as part of the
pre-delivery inspection. The dealer can check for and correct any steering
problems before you take delivery.
