Visual Checking of Wheel
Installation Condition
Visually check the condition of installation
of each disc wheel.
1. Check that there are no missing
wheel bolts and wheel nuts.
2. Check each disc wheel to see if there
is any rust seepage from wheel bolts
or nuts. Also check the disc wheel for
cracks or other damage.
3. Check the end of each wheel stud for
proper length of protrusion from the
wheel nut. The protrusion should be
uniform among all studs on a wheel
and among all wheels.
CAUTION
• Any abnormality in wheel installation
is likely to lead to loose or missing
wheel nuts and/or broken wheel
studs.
Checking Wheel Installation
Condition with an Inspection
Hammer
Place your fingers on the bottom of each
wheel nut and tap the top flat portion of the
nut with an inspection hammer or small
hammer in the tightening direction.
There may be some defect in a nut or its
stud if the vibration you feel by the fingers
is different from the other nuts or if the
sound it produces is not clear.
CAUTION
• If you detect any abnormal condition
with a wheel nut and stud during this
inspection, it is likely that the nut is
loose or the stud is broken.
