Toyota growl

Some 2010-2011 part-time Toyota 4WD 4Runner SR5 vehicles may exhibit a growl or rumble noise from the front differential assembly when the vehicle is in motion in 2WD.

1. Test drive to confirm the condition.

2. Using ChassisEAR or equivalent, confirm that the noise is loudest from the left side of the differential assembly when in 2WD. If the noise goes away when the vehicle is placed in 4WD, this bulletin applies.

3. Replace the front differential assembly.

4. Inspect the left front axle assembly for wear. If wear is present, replace the left front axle.

5. Test drive to confirm the repair.
