Note :

 
The air pressure of the tire should be maintained as indicated in the label instruction on the driver's
door or frame of driver's door.
Lower pressure can cause burst and adverse vehicle handling.
On the other hand, higher pressure can cause shock-burst and reduce gripping effect.

INSPECTION AND REPAIR
Make necessary correction or parts replacement if wear, damage or any other abnormal conditions are found
through inspection.




Visual Check
Inspect all disassembled parts for wear, damage or other
abnormal conditions.

Balancing Wheel and Tire
On-vehicle Balancing

On-Vehicle balancing methods very 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.
