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.

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 PERFORMING SERVICE ON OR NEAR  THE SRS
COMPONENTS OR THE SRS WIRING, REFER TO
THE SRS SERVICE INFORMATION. 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 specifications. Following these
instructions can help you avoid damage  to parts and
systems.

General Description

Intellignet suspension control uses a microcomputer as a
control unit to judge running conditions including engine
revolution from Powertrain Control Module, vehicle speed
from vehicle speed sensor, a brake switch signal, and
vertical and lateral G-sensor signal, then sets optimum
damping force so that best running stability can be
achieved.
