Check center bearing for noise and damage. If malfunction is detected, replace propeller shaft assembly.
caution
Never disassemble center bearing.
INSPECTION AFTER INSTALLATION
After assembly, perform a driving test to check propeller shaft vibration. If vibration occurred, separate propeller shaft from final drive. Reinstall propeller shaft by changing the phase between companion flange and propeller shaft by the one bolt hole at a time. Then perform driving test and check propeller shaft vibration again at each point.
