APPEARANCE AND NOISE INSPECTION

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

• Check the bearings for noise and damage. Repair or replace the bearings as necessary.

PROPELLER SHAFT VIBRATION

If a vibration is present at high speed, inspect the propeller shaft runout first.
1. Measure the runout of the propeller shaft tube at several points

by rotating the final drive companion flange with your hands.

Refer to

DLN-134, "General Specification"

.

2. If the runout exceeds specifications, disconnect the propeller

shaft at the final drive companion flange; then rotate the com-

panion flange 90

°, 180° and 270° and reconnect the propeller

shaft.

3. Check the runout again. If the runout still exceeds specifications,

replace the propeller shaft assembly. Refer to

DLN-134, "Gen-

eral Specification"

.

4. After installation, check for vibration by driving the vehicle.
