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 bolt if
the vibration you feel is different from the
other nuts or if the sound it produces is not
clear.
1. Check that there are no missing
wheel bolts and wheel nuts.
2. Check each disc wheel to see if there
is any rust apparent on wheel bolts
or nuts. Also, check to see if the
disc wheel is cracked or otherwise
damaged.
3. Check the end of each wheel bolt
to make sure it protrudes the proper
length from the wheel nut. The
protrusion should be uniform among
all bolts 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
bolts.
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.
