38. Check for indications of loose wheel nuts or rim
nuts and examine each wheel component.
Check the wheel nuts or rim nuts for indications of
looseness. Remove all dirt and foreign material
from the assembly. Dirt or rust streaks from the
stud holes, metal buildup around stud holes or out-
of-round or worn stud holes may be caused by
loose wheel nuts. See Group 40 of the Cargo
Maintenance Manual for torque specifications and
the correct tightening sequence.
Examine the wheel assembly components (includ-
ing rims, rings, flanges, studs, and nuts) for cracks
or other damage.

and hubs and see Group 40 of the same manual
for wheel and tire servicing. Replace broken,
cracked, badly worn, bent, rusty, or sprung rings
and rims. Be sure that the rim base, lockring, and
side ring are matched according to size and type.
WARNING
Have any worn or damaged wheel components re-
placed by a qualified person using the wheel manu-
facturer's instructions and the wheel industry's
standard safety precautions and equipment. Other-
wise a vehicle or workshop accident could occur,
possibly resulting in serious personal injury or
death.
CAUTION
Insufficient wheel nut (rim nut) torque can cause
wheel shimmy, resulting in wheel damage, stud
breakage, and extreme tire tread wear. Excessive
wheel nut torque can break studs, damage threads,
and crack discs in the stud hole area. Use the rec-
ommended torque values and follow the proper
tightening sequence.
