We recommend you have the front suspension and steering alignment checked and adjusted
after you have fully loaded the vehicle as part of the vehicle maintenance. Thereafter, it is
your responsibility to have the alignment inspected periodically to maintain vehicle steering
performance and prevent uneven tire wear as part of your normal maintenance.
™ 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-deliv-
ery inspection. The dealer can check for and correct any steering problems
before you take delivery.
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
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.
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,
