This bulletin provides information relating to some SPOPORTAGE (KM) vehicles produced from 10/28/2004 ~ 9/30/2007 with 4WD system which may exhibit a droning noise originating from the 4WD coupling while driving between 12 ~ 37 MPH. The cause of this condition may be the internal part of the 4WD coupling assembly is binding due to a possible damaged roller bearing.

Do NOT replace the rear differential assembly for noise concerns until the 4WD coupler assembly has been checked for proper operation.
