2009 – 2012 GT-R
RATTLE FROM FLYWHEEL HOUSING
The Applied Vehicles and Parts Information in this bulletin have been amended.
Please discard previous versions of this bulletin.

APPLIED VEHICLES: 2009 – 2012 GT-R (R35)
This bulletin DOES NOT APPLY to 2013 and later (newer) GT-R.

IF YOU CONFIRM
A rattle noise coming directly from the rear tail shaft area of the flywheel housing,
NOTE:


The GT-R transmission has different operating characteristics than a typical
passenger car. Because of this, various driveline rattle noises may be heard during
some driving conditions. These normal characteristic noises do not indicate a
malfunction. Refer to the Owner’s Manual for addition information on transmission
operating characteristics.



When placed on a lift and listening from under the vehicle, the source of the typical
GT-R driveline rattle noise is from the center of the main driveshaft or near the rear
mounted transmission. A rattle noise caused by the flywheel housing will come
directly from the rear tail shaft area of the flywheel housing.



The rattle noise for this incident—if it should occur—can be duplicated by putting the
transmission in Park or Neutral, then slightly accelerating and decelerating the
engine.

ACTION
Replace the Flywheel housing with the new one listed in the Parts Information.

IMPORTANT: The purpose of ACTIONS (above) is to give you a quick idea of the work you will be
performing. You MUST closely follow the entire Service Procedure as it contains information that is
essential to successfully completing this repair.
Nissan 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 Nissan dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE

1. Remove the engine from the vehicle using a suitable engine caddy or support table.


Refer to the Electronic Service Manual (ESM), Section EM, for engine removal
information.

NOTE: Each GT-R certified dealer received a “Nissan GT-R Service Requirements
Resource Guide & DVD” kit. The information in this kit is very helpful for engine
removal. The guide and video are also available on Nissan Virtual Academy.
