- If center bearing is noisy or damaged, replace propeller shaft assembly.
VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
Scheme 29
- Measure propeller shaft runout at runout measuring points by rotating final drive companion flange with hands. Limit Propeller shaft runout: Refer to " «PROPELLER SHAFT RUNOUT»(ref-295114-S23326992822008081400000) ".
- If runout still exceeds specifications, separate propeller shaft at final drive companion flange or transfer companion flange; then rotate companion flange 90, 180, 270 degrees and install propeller shaft. see scheme 36: Measuring Propeller Shaft Runout
- Check runout again. If runout still exceeds specifications, replace propeller shaft assembly.
- Check the vibration by driving vehicle.
