THIS WOULD ALLOW EXCESSIVE MOVEMENT OF THE BEARING-HUBASSEMBLY RELATIVE TO THE REAR AXLE FLANGE AND COULD CAUSE ELONGATION ANDEVENTUAL SEPARATION OF THE ATTACHING BOLTS FROM THE REAR AXLE FLANGE. IF THISWERE TO OCCUR WHILE THE VEHICLE WAS IN MOTION, THE AFFECTED TIRE AND WHEEL COULDTRACK ERRATICALLY, EVENTUALLY CAUSING FAILURE OF THE OTHER ATTACHING BOLTS. THETIRE AND WHEEL ASSEMBLY COULD SEPARATE FROM THE VEHICLE WHICH COULD RESULT IN AVEHICLE ACCIDENT.

TIGHTEN REAR AXLE BEARING-HUB ASSEMBLY FASTENERS, AND REPLACE ALL THE FASTENERS ON A WHEEL IF TWO OR MORE BOLTS ARE FOUND TO BE LOOSE.

ALSO, THE DRIVER CAN PLACE THE GEAR SELECTOR IN DRIVE OR REVERSE WITHOUTTURNING THE ENGINE OFF AND THE TRANSAXLE MAY NOT BE IN THE POSITION INDICATED,CAUSING THE VEHICLE TO MOVE IN THE OPPOSITE DIRECTION. BOTH CONDITIONS CANRESULT IN A VEHICLE ACCIDENT WITHOUT PRIOR WARNING.

INSTALL TWO TRANSAXLE SHIFT CONTROL CABLE RETAINING CLIPS.

IF THE SECONDARY HOOD LATCH IS NOT PROPERLY ENGAGED, ANDTHE PRIMARY HOOD LATCH WAS ALSO NOT ENGAGED, THE HOOD COULD OPEN AND CONTACT THEWINDSHIELD WHILE THE VEHICLE WAS IN MOTION, REDUCING THE FORWARD VISION AREA OFTHE DRIVER AND RESULTING IN A POSSIBLE VEHICLE ACCIDENT WITHOUT PRIOR WARNING.

INSTALL A NEW SECONDARY HOOD LATCH ASSEMBLY.

REPLACE PARKING BRAKE LEVER ASSEMBLY.

IF THE SECONDARY HOOD LATCH IS NOT ENGAGED, AND THEPRIMARY HOOD LATCH WAS ALSO NOT ENGAGED, THE HOOD COULD OPEN UNEXPECTEDLY. IFTHIS OCCURS WHILE THE VEHICLE IS IN MOTION, THE HOOD MAY CONTACT THE WINDSHIELD,REDUCING THE FORWARD VISION AREA OF THE DRIVER AND A VEHICLE CRASH COULD OCCUR.

INSPECT HOOD LATCH ASSEMBLIES AND, WHERE NECESSARY, INSTALL A NEW SECONDARY HOOD LATCH SPRING.

IF THIS CONDITION EXISTS AND SHAFT DISENGAGEMENT OCCURS, LOSS OF STEERING CONTROL WILL BE EXPERIENCED BY THE DRIVER WHICH COULD RESULT IN AN ACCIDENT.

INSTALL PINCH BOLT.

VEHICLES WOULD NOT MEET THE REQUIREMENTS OF FMVSS 101AND 105.

REPLACE THE PROM IN THE BODY COMPUTER MODULE TO PREVENT THIS CONDITION FROM OCCURRING.

REPLACE THE SAFETY BELTS IF THE LOCKUP OCCURS.

A BENT SECONDARY HOOD LATCH COULD LEAD TO THE PRIMARYLATCH NOT BEING FULLY ENGAGED, ALLOWING THE HOOD TO UNEXPECTEDLY OPEN. IF THISWERE TO OCCUR WHILE THE VEHICLE WAS IN MOTION, THE HOOD MAY CONTACT THEWINDSHIELD, REDUCING THE FORWARD VISION AREA OF THE DRIVER AND A VEHICLE CRASHCOULD OCCUR WITHOUT PRIOR WARNING.

REPLACE THE PRIMARY HOOD LATCH ASSEMBLY, THE SECONDARY HOOD LATCH ASSEMBLY, AND THE SUPPORT BRACKET.

THE DISENGAGED CABLE COULD FALSELY INDICATE TRANSMISSIONGEAR POSITION, AND THE VEHICLE MIGHT BE LEFT IN REVERSE OR DRIVE WHEN THE DRIVERMOVED THE GEAR SELECTOR TO PARK OR THE OPPOSITE DIRECTION. A VEHICLE LEFT ON ANINCLINE WITHOUT PARKING BRAKES WHEN THE GEAR SELECTOR IS PLACED IN PARK COULDMOVE. EITHER CASE RESULTS IN UNEXPECTED VEHICLE MOVEMENT WITHOUT PRIOR WARNINGAND COULD CAUSE A VEHICLE ACCIDENT.

INSTALL A TRANSAXLE SHIFT CONTROL CABLE RETAINING CLIP ON THE SHIFT CONTROL CABLE BRACKET ON TOP OF TRANSAXLE.

THE LOOSE PIVOT BOLT COULD ALLOW THE PARKING BRAKES TORELEASE AFTER THEY HAVE BEEN SET MANUALLY; IF THE BOLT FALLS OFF WHEN THEAUTOMATIC APPLY PARKING BRAKE IS SET, THERE IS INSUFFICIENT BRAKING TO HOLD THEVEHICLE IF IT IS PARKED ON AN INCLINE. BOTH OF THESE CONDITIONS COULD RESULT INVEHICLE MOVEMENT WITHOUT PRIOR WARNING AND POSSIBLY IN AN ACCIDENT.

TORQUE PIVOT BOLT TO SPECIFICATIONS.

THIS CONDITION LEADS TO INCREASED STOPPING DISTANCE, ANDSHOULD MINIMUM STOPPING DISTANCE BE REQUIRED, IT COULD RESULT IN AN ACCIDENTWITHOUT WARNING.

REPLACE BOTH REAR AXLE HUBS.

IN THE EVENT OF ROLLOVER ACCIDENT, AN OUT OF POSTIONSEAL COULD ALLOW FUEL SPILLAGE IN EXCESS OF THE AMOUNT PRESCRIBED BY FMVSS 301.SPILLED FUEL COULD IGNITE NEAR AN IGNITION SOURCE.

CHAFING OR SERATION OF FRONT BRAKE HOSE COULD RESULT IN ASUDDEN FAILURE OF FRONT HYDRAULIC BRAKE SYSTEM.

REPLACE FRONT WHEELHOUSE SPLASH SHIELD.

THIS COULD ALLOW STEERING WHEEL TO SEPARATE FROM STEERINGCOLUMN; LOSS OF VEHICLE CONTROL AND A CRASH COULD OCCUR WITHOUT PRIOR WARNING.

TIGHTEN THE NUT TO THE PROPER TORQUE AS NECESSARY.

REDUCED REFLECTIVE AREA ON OUTSIDE REAR VIEW MIRRORSREDUCES THE DRIVER'S APPARENT AREA OF VISIBILITY IN THE REAR OF THE TRUCK. THISREDUCED AREA OF VISIBILITY INCREASES THE LIKELIHOOD OF VEHICLE COLLISION.

REPLACE THE NON-CONFORMING REAR VIEW MIRRORS.

IN THE EVENT OF A SUDDEN STOP OR VEHICLE IMPACT, ANUNLOCKED SEAT BACK WOULD INCREASE THE RISK OF INJURY TO THE SEAT OCCUPANT.
