The problem
ON CERTAIN TRUCKS BUILT WITH IROS REAR AIR SUSPENSION SYSTEMS, FOUR REAR SUSPENSION FASTENERS MAY NOT BE TIGHTENED SUFFICIENTLY. THIS HARDWARE CONNECTS THE MAIN SUPPORT MEMBERS OF THE REAR SUSPENSION TO THE HANGER BRACKETS.
Risk
THIS CONNECTION COULD FAIL IF THE NUTS WORKED THEIR WAY LOOSE OR OFF, OR THE BOLTS BROKE FROM FATIGUE. A FAILURE OF THESE FASTENERS COULD RESULT IN SEPARATION OF THE MAIN SUPPORT FROM THE HANGER BRACKET POSSIBLY RESULTING IN A SUDDEN LOSS OF CONTROL OF THE VEHICLE, WHICH COULD RESULT IN A CRASH.
What owners should do
DEALERS WILL REPLACE ALL FOUR BOLTS AND TIGHTEN THE BOLTS PROPERLY. THE RECALL BEGAN ON NOVEMBER 5, 2004. OWNERS SHOULD CONTACT INTERNATIONAL AT 1-800-448-7825.
