PROPELLER SHAFT VIBRATION
NOTE: If vibration is present at high speed, check propeller shaft run out first, then check mounting between propeller shaft and companion flange.
1. Measure the run out of the propeller shaft tube at several points by rotating the final drive companion flange with your hands.
Propeller shaft runout limit: 1.02 mm (0.0402 inch) or less
2. If the run out still exceeds specifications, disconnect the propeller shaft at the final drive companion flange; then rotate the companion flange 90°,
180°, 270° degrees and reconnect propeller shaft.
3. Check the run out again. If the run out still exceeds specifications, replace the propeller shaft assembly.
4. After installation, check for vibration by driving vehicle.
