AUTOMOTIVE INTELLIGENCE
repairs include the removal of the wheel
from the rim followed by an inspection
of the puncture area. If the puncture is
within the guidelines, then the best practice
is to use the proper size patch and
plug service patch with the proper tools
and procedures to ensure an effective
repair (Figure 3). Additionally, there are
tires equipped with special acoustic foam
inserts that require special handling during
puncture service.
WHEEL ALIGNMENT
A wheel alignment offers the technician
the opportunity to fine-tune the operational
characteristics as they relate to
steering, handling, and braking performance.
Additionally, vehicles equipped
with advanced driver assistance systems
(ADAS) may require additional services
such as camera/radar aiming, steering
angle resets, and more. Service information
procedures should be consulted on
late-model vehicles and especially for
ADAS-equipped vehicles.
TIRE PRESSURE MONITORING
SYSTEMS (TPMS)
When servicing wheels and tires with
TPMS sensors, the proper service procedures
usually include the replacement
of the seals, gaskets, and valve cores. Be
sure to reassemble using the proper torque
levels which can be performed by using
torque tools.
NOISE VIBRATION AND
HARSHNESS (NVH)
You may find yourself dealing with a
vibration complaint on a vehicle occurring
at certain speeds and road conditions.
Oftentimes these can be difficult
to address. There are a few NVH
measurement tools out there in the
marketplace that can be used to narrow
down such vibrations. Automotive
Test Solutions offers their Intelligent
Vibration Analyzer to help with identifying
vibration sources and provides an
easy-to-understand visual data map of
the vehicle. Pico Technology also offers
an NVH tool that can be added on their
four-channel scope.

Figure 4 - Major tire damage
The tool offers a graphical display
of the vibration levels and what their
sources are. The system uses a single
three-axis accelerometer as opposed to
the four-channel system from ATS.
TIRE INSPECTION
A thorough inspection of the tires during
service should always include checking
the complete tire including date codes,
sizes, and thread condition. The tire in
Figure 4 met up with some bad debris on
the road and at first glance, it didn't look
too bad. A closer inspection revealed a
sliced-out section of the tire. Wheel and
tire service has evolved, placing additional
demands on the service professional.
Please make sure that your shop
