CONSUMER COMPLAINTS REPORT THAT BOLTS WHICH RETAIN THE AXLE PIVOT BRACKET TO THE FRAME CROSS MEMBER CAN LOOSEN OR FAIL, CAUSING THE INBOARD END OR THE AXLE TO BECOME DETACHED FROM THE VEHICLE.OWNERS ALLEGE THAT THIS COULD RESULT IN LOSS OF STEERING CONTROL, HOWEVER THE COMPLAINT DATA SHOWS ONLY ONE INCIDENT WHERE THE VEHICLE LEFT THE ROADWAY FOLLOWING AXLE SEPARATION, WITH NO DAMAGE TO THE VEHICLE.IN ADDITION TO THE 225 CONSUMER COMPLAINTS, THERE WERE 4,315 WARRANTY CLAIMS RELATED TO THE FRONT SUSPENSION AND MEMBERS, AND 22 VEHICLES WERE REPLACED FOR GOODWILL.DOCUMENTS SUBMITTED BY FORD, UNDER REQUEST FOR CONFIDENTIAL TREATMENT INDICATE THAT THE BOLTS WERE INADEQUATE FOR THE DURABILITY REQUIREMENTS OF THE VEHICLE.ALSO, BOLTS WERE FOUND TO HAVE BEEN INADEQUATELY TORQUED AT ONE OR MORE ASSEMBLY PLANTS.OTHER FACTORS, SUCH AS WAX TREATMENT OF THE FRAME, CONTRIBUTED TO THE PROBLEM.INCREASED BOLT DIAMETER AND INCREASED TORQUE APPARENTLY CORRECTED THE PROBLEM.A SERVICE BULLETIN, 96-20-13, WAS ISSUED TO ADVISE DEALERS OF THIS CORRECTIVE ACTION.IN THESE DOCUMENTS, FORD ALSO REPORTED THAT A VEHICLE, EQUIPPED FOR SIMULTANEOUS CATASTROPHIC FAILURE OF ALL PIVOT BRACKET FASTENERS, WAS EVALUATED RESULTING IN A SLIGHT VEHICLE PULL TO ONE SIDE WITH NO LOSS OF VEHICLE CONTROL.ODI HAS NOT REPLICATED FORD'S VEHICLE TESTING, HOWEVER ANALYSIS OF THE DESIGN OF THE FRONT SUSPENSION INDICATES THAT EVEN IF THE INBOARD END OF THEAXLE BECAME DISCONNECTED FROM THE FRAME, THE OUTBOARD END WOULD REMAIN FIRMLY ATTACHED TO THE LEAF SPRING WITH TWO U-BOLTS.THIS WOULD RETAIN THE WHEEL IN ITS APPROXIMATE POSITION, ALTHOUGH THE WHEEL ALIGNMENT WOULD BE GREATLY IN ERROR.THEREFORE IT IS UNLIKELY THAT CONTROL OF THE VEHICLE WOULD BE LOST.OWNERS REPROT MANY SIGNIFICANT NOISES IN THE SUSPENSION, SUCH AS CREAKING, GROANING, CLUNKING, AND SQUEAKING, PRIOR TO NOTICING ANY SEPARATION OF THE AXLE.THIS PROVIDES WARNING OF THE LOOSENING OF THE BOLTS TO THE DRIVER, AND SHOULD NOT BE IGNORED.FORD HAS STATED THAT REPAIRS WILL BE COVERED UNDER THE VEHICLE'S BUMPER WARRANTY.COMPLAINTS ABOUT WARRANTY COVERAGE BY A FORD DEALER SHOULD BE ADDRESSED TO FORD, OR TO APPROPRIATE STATE AND LOCAL AGENCIES.A SAFETY-RELATED DEFECT TREND HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.

FORD HAS ACKNOWLEDGED A SERIOUS PROBLEM WITH THE ACCESSORY DRIVE BELT SYSTEM (SERPENTINE BELT) IN THE SUBJECT VEHICLES.SEVERAL SERVICE BULLETINS HAVE BEEN ISSUED TO ADDRESS CONCERNS RELATED TO BELT TRACKING OR WEAR.FORD MAINTAINS THAT THE SUBJECT CONDITION DOES NOT PRESENT AN UNREASONABLE RISK TO HIGHWAY SAFETY, ARGUING THAT THE LOW INCIDENCE OF FAILURES ALLEGING SAFETY CONSEQUENCES (I.E., FIRES, FLUID LEAKS, AND/OR ACCIDENTS) IS STRONG EVIDENCE IN SUPPORT OF THIS CLAIM.FORD HAS INDICATED RECEIPT OF 4,445 FIELD REPORTS AND 46891 WARRANTY CLAIMS CONCERNING THE SUBJECT CONDITION. FORD MAINTAINS THAT THE LOW NUMBER OF REPORTED HOSE RUPTURES AND/OR FIRES, RELATIVE TO TOTAL BELT FAILURES, SHOWS THAT THE PROBLEM IS A DURABILITY CONCERN THAT PRESENTS VERY LITTLE RISK TO MOTOR VEHICLE SAFETY.FORD INTENDS TO ADDRESS THE PROBLEMIN A SERVICE BULLETIN SCHEDULED FOR PUBLICATION THE WEEK OF MARCH 13, 1995.ODI HAS RECEIVED SEVERAL CLAIMS ALLEGING THAT INCIDENTS OF BELT FAILURE ARE CAUSING COLLATERAL DAMAGE TO ADJACENT FLUID SYSTEMS (E.G., POWER STEERING HOSE, COOLANT HOSE, AND AUTOMATIC TRANSMISSION OIL COOLER HOSE).RELEASE OF THESE FLUIDS WITHIN THE ENGINE COMPARTMENT MAY RESULT IN A VEHICLE FIRE, IF EXPOSED TO A SUFFICIENTLY HOT SURFACE AREA.THE AUTOIGNITION TEMPERATURE FOR TRANSMISSION OIL MAY BE AS LOW AS 300 C (570 F), WHILE POWER STEERING FLUID AND ENGINE COOLANT ARE GENERALLY HARDER TO IGNITE (CLOSER TO 500 DEGREE C (900 DEGREEF)).DAMAGE TO BATTERY CABLE INSULATION HAS ALSO BEEN ALLEGED AS A CONSEQUENCE OF SERPENTINE BELT FAILURE.ODI HAS RECEIVED FOUR REPORTS ALLEGING FAILURE OF ADJACENT FLUID SYSTEM HOSES FROM CONTACT WITH A BROKEN SERPENTINE BELT.ONE REPORT INVOLVED AN ECONOLINE RV CUTAWAY CHASSIS WITH A 7.3L V-8 NAVISTAR ENGINE, USED IN THE TRANSPORT OF DISABLED CHILDREN.AN ENGINE COMPARTMENT FIRE DESTROYED THE VEHICLE IN NOVEMBER 1994.THE FIRE IS ALLEGED TO HAVE BEEN CAUSED WHEN THE SERPENTINE BELT BROKE AT HIGHWAY SPEED AND RUPTURED A TRANSMISSION COLLER LINE. THE REPORT ALLEGES FINDING BELT FRAGMENTS AND TRACES OF TRANSMISSION FLUID UP THE ROAD FROM THE FIRE SCENE, NEAR WHERE THE DRIVER HAD HEARD A POP JUST PRIOR TO THE FIRE.THE DRIVER REPORTEDLY SUSTAINED MINOR BURN INJURIES WHILE EVACUATING PASSENGERS.OWNER REPORTS ALSO ALLEGE SOME LOSS OF VEHICLE CONTROL OCCURS WITH THE BELT FAILURES, DUE TO THE LOSS OF POWER ASSIST CAPABILITY TO THE BRAKING AND STEERING SYSTEMS.THE SERPENTINE BELT DRIVES THE POWER STEERING PUMP AND THE VACUUM PUMP FOR THE BRAKE BOOSTER IN THE SUBJECT VEHICLES.AS STATED IN FORD BULLETIN 93-23-27: SOME DIESEL POWERED VEHICLES ARE EXPERIENCING DRIVE BELT TRACKING CONCERNS.THIS IS CAUSED BY FRONT END ACCESSORY DRIVE (FEAD) MISALIGNMENT, WHICH MAY RESULT IN THE BELT COMING OFF THE ACCESSORY DRIVE PULLEYS.IF THIS OCCURS, SEVERAL WARNING LIGHTS WILL ILLUMINATE AND THE VEHICLE WILL LOSE ALTERNATOR AND A/C FUNCTION AND WATER PUMP CIRCULATION.IN ADDITION, STEERING EFFORTS WILL INCREASE AND, AFTER ONE OR A FEW BRAKE APPLICATIONS, BRAKE EFFORTS WIL PROGRESSIVELY INCREASE. THERE ARE THREE ODI COMPLAINTS AND FIVE FORD COMPLAINTS, NOT INCLUDED IN THE FAILURE REPORT SUMMARY OF THIS RESUME, ALLEGING THAT THE REDUCTIONIN VEHICLE CONTROL ASSOCIATED WITH ACESSORY DRIVE BELT FAILURE RESULTED IN AN ACCIDENT.THIS INVESTIGATION IS BEING UPGRADED TO FURTHER ANALYZE THE POTENTIAL SAFETY CONSEQUENCES OF SERPENTINE BELT FAILURE IN THE SUBJECT VEHICLES.
