IF YOU CONFIRM
There is a vibration or judder feeling from the rear of the vehicle during the following conditions:




When making turns
On dry roads
At low speeds (under 40 MPH)

And


The above vibration does not occur if the electric controlled coupling is electrically disconnected.

NOTE: In some cases, electrically disconnecting the electric controlled coupling may not eliminate the vibration.
In these cases, further confirm the incident by removing the rear propeller shaft and retest. If the vibration does
not occur with the rear propeller shaft removed, the incident is confirmed.
NOTE: Tire size, brand or tread pattern mismatches can cause similar symptoms. To avoid tire related
mismatch vibration, it is recommended that when tires need to be replaced, all tires are replaced at the same
time with tires of the proper size, same brand and pattern.

Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained
individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe
that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti retailer to determine if this
applies to your vehicle.
