Front wheels
Rims:Check for damaged or bent rims. Rims should
not have welding repairs and no rust trails that
indicate it is loose on the wheel.
Lug nuts:Make sure all lug nuts are present and not
loose (look for rust trails around the lug nuts).
There should be no cracks radiating from the
lug bolt holes or distortion of the bolt holes.
Hub oil seal:Check wheel hub oil seal for leaks, and if sight
glass if present, check to see that the oil level
is adequate.
Oil-lubricated front
wheel bearing:If the hubcap has a transparent window, check
for proper lubrication level. If the hubcap does
not have a transparent window, remove the
rubber fill-plug and check for proper level.
If a wheel must be changed, obtain expert tire service help.
Mounting and un-mounting of tires should only be performed by
a qualified technician using necessary safety procedures and
equipment, otherwise the result could be property damage, personal
injury or death.
Driver/Fuel area
Fuel tank:Make sure the fuel tank and caps are secure.
Make sure there is no damage to the tank.
Leaks:Check for any leaks from the fuel tanks.

Vehicle Inspection Guide

•Always loosen rim clamps before complete removal of nut from stud
(cast spoke wheels). With loosened nuts on stud, strike clamps with a
heavy hammer and be sure each clamp is loose.
•Always deflate tires completely before removing locks or side rings.
•Always inflate tires in a safety cage.
•Never mix rim side rings or lock rings of different types,
manufacturers or sizes.
•Never use cracked, bent or badly rusted parts.
•Never re-inflate flat tires on-vehicle; use the spare tire.
•Never add air until each side ring or lock ring is fully seated.
•Never hammer side ring or lock ring on a partially- or fully-inflated
tire.
Proper torque
It is important to tighten and maintain wheel and rim mounting nuts to
the proper torque. Loose nuts or over-tightened nuts can lead to
premature wear and possible failure of the wheel and/or mounting
hardware.
Changing wheel types
Consult your dealer or wheel/rim distributor before attempting any wheel
or fastener changes.
Use only the same type and style wheels and mounting hardware
to replace original parts. Failure to do so may result in an
assembly that looks fine, but does not fit together properly. This could
possibly cause wheel or fastener failures which could result in property
damage, personal injury or death.
Note:Do not attempt to mix stud-piloted wheels or fasteners with
hub-piloted wheels or fasteners.
Note:Do not change from aluminum wheels to steel wheels or
vice-versa without changing the mounting hardware required or, with
flange-nut mounting systems, changing the hub and stud assembly.
