WHEEL AND TIRE SYSTEM

480RS013

Legend

(1) Heavy Spot Wheel Shimmy
(2) Add Balance Weights Here

Dynamic balance is the equal distribution of weight on
each side of the wheel center-line so that when the tire
spins there is no tendency for the assembly to move from
side to side.  Assemblies that are dynamically unbalanced
may cause shimmy.

Legend

(1) Heavy Spot Wheel Hop
(2) Add Balance Weights Here

WARNING: STONES SHOULD BE REMOVED FROM
THE TREAD TO AVOID OPERATOR INJURY DURING
SPIN BALANCING AND TO OBTAIN A GOOD
BALANCE.

Balancing Wheel and Tire

On-vehicle Balancing

On-Vehicle balancing methods vary with equipment and
tool manufacturers.  Be sure to follow each
manufacturer’s instructions during balancing operation.

Off-vehicle Balancing

Most electronic off-vehicle balancers are more accurate
than the on-vehicle spin balancers.  They are easy to use
and give a dynamic balance.  Although they do not correct
for drum or disc unbalance (as on- vehicle spin balancing
does), they are very accurate.

Service Precaution

WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM(SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE REFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING, REFER TO
THE SRS SERVICE INFOMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.

CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED , do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally,such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener.  When
you install fasteners, use the correct tightening
sequence and specification.  Following these
instructions can help you avoid damage to parts and
systems.
