Repair Instructions
Wheel Discs InspectionS6RW0D2406006
Inspect each wheel disc for dents, distortion and cracks.
A disc in badly damaged condition must be replaced.
Wheel Balance Inspection and AdjustmentS6RW0D2406001
Refer to “Balancing Wheels Description”.
Deposits of mud, etc. must be cleaned from inside of rim.
WARNING!
Stones should be removed from the tread in
order to avoid operator injury during spin
balancing and to obtain good balance.

Each tire should be inspected for any damage, then
balanced according to equipment manufacturer’s
recommendation.
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 (two plane) balance. Although they
do not correct for drum or disc unbalance as does on-
vehicle spin balancing, this is overcome by their
accuracy, usually to within 1/8 ounce.
On-Vehicle Balancing
On-vehicle balancing methods vary with equipment and
tool manufacturers. Be sure to follow each
manufacturer’s instructions during balancing operation.
WARNING!
Wheel spin should be limited to 55 km/h (35
mph) as indicated on speedometer.
This limit is necessary because speedometer
only indicates one-half of actual wheel speed
when one drive wheel is spinning and the
other drive wheel is stopped.
Unless care is taken in limiting drive wheel
spin, spinning wheel can reach excessive
speeds. This can result in possible tire
disintegration or differential failure, which
could cause serious personal injury or
extensive vehicle damage.

CAUTION!
For vehicle equipped with ABS, using on-
vehicle balancing method with ignition
switch ON may set malfunction diagnostic
trouble code (DTC) of ABS even when system
is in good condition.
Never turn ignition switch ON while spinning
wheel.

Tire RotationS6RW0D2406002
To equalize wear, rotate tires periodically as shown in
figure.
Refer to “Wheel (with Tire) Removal and Installation”.
