Abnormal Buzz/Groan Noise at 20 - 30 mph From Front Transfer Case
Confirmation Procedure
1. Confirm the vehicle exhibits an abnormal buzz/groan noise from the front transfer case
during one or both of the following conditions.

Driving at 20 – 30 mph when accelerating from a stop during AWD system
disconnect timing.

Driving at 20 – 13 mph on deceleration during AWD system connect timing.
Refer to the buzz/groan noise example video link:
Buzz/Groan Noise Example Video
NOTE
 Use ChassisEAR™ to confirm the noise is coming from the front transfer case.
 Monitor the 4WD ECU Data List “Front and rear axle coupling position sensor status” to confirm
the noise is occurring at AWD system disconnect and/or connect timing.
HINT
While driving above 20 mph, the system can be manually switched back and forth from disconnect
to connect by switching drive mode from Normal to Sport.
Does the vehicle exhibit an abnormal buzz/groan noise from the front transfer case during
one or both conditions described above?

YES — Review and complete the rest of the Repair Procedure in this bulletin.

NO — This bulletin does NOT apply. Continue diagnosis using the applicable
Repair Manual.
