BACKGROUND
A rotating sound may be heard from the viscous coupling/housing on some AWD/XC vehicles. The sound occurs most frequently at low speed when
turning, and during warm weather at light to medium throttle.
This sound can be caused by movement of the outer bearing race in the torque tube housing. This service bulletin describes how to minimize this sound.
