Maintenance: NVH Infiniti FX50 II рестайлинг

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.

Scheme 47

Scheme 48

1. With a dial indicator, measure propeller shaft runout at runout measuring points by rotating final drive companion flange with hands. Propeller shaft runout: Refer to " «PROPELLER SHAFT RUNOUT»(ref-524016-S31247803142013012500000) ". Propeller shaft runout measuring point (Point " delta") VQ35HR Dimension A: 381.5 mm (15.02 in) VK50VE Dimension A: 386.5 mm (15.22 in)
2. If runout still exceeds specifications, separate propeller shaft at final drive companion flange; then change the phase between companion flange and propeller shaft by the one bolt hole at a time and install propeller shaft.
3. If runout is more than the limit value, remove and check propeller shaft.
4. Check the vibration by driving vehicle.

1. Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
2. If center bearing is noisy or damaged, replace propeller shaft assembly.

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