THIS CHANGE AFFECTED THE LEAF SPRINGS AND APPEARS TO HAVE HAD A POSITIVE EFFECT IN CORRECTING THE BUCKLE ISSUES THAT WERE EXPERIENCED IN THE EARLY PRODUCTION VEHICLES.THE COMPLAINT REPORT TREND IS DOWN AND THE FREQUENCY OF CONSUMER REPORTS IN CY 2006 HAS DECLINED TO THAT OF CY 2004.SEE DOCUMENT FILE FOR ADDITIONAL INFORMATION REGARDING THIS RESUME.
