NOISE

Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.

VIBRATION

If vibration is present at high speed, inspect propeller shaft runout
first.
1.

With a dial indicator, measure propeller shaft runout at runout
measuring points by rotating final drive companion flange with
hands.

2.

If runout still exceeds specifications, separate propeller shaft at
final drive companion flange; then rotate companion flange 90, 180, 270 degrees and install propeller
shaft.

3.

Check runout again. If runout still exceeds specifications, replace propeller shaft assembly. 

4.

Check the vibration by driving vehicle.

INFOID:0000000006394852

BALANCING WHEELS (BONDING WEIGHT TYPE)

Preparation Before Adjustment

Using releasing agent, remove double-faced adhesive tape from the road wheel.

CAUTION:

• Be careful not to scratch the road wheel during removal.
• After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road

wheel.

Wheel Balance Adjustment

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting, select
and adjust a drive-in weight mode suitable for road wheels.

1.

Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine.

2.

When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer
unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight
with a value closest to the calculated value above and install to the designated outer position of, or at the
designated angle in relation to the road wheel.

CAUTION:

• Never install the inner balance weight before installing the outer balance weight.
• Before installing the balance weight, always to clean the mating surface of the road wheel.
