VEHICLE DESCRIPTION: QUAD CAB PICKUP TRUCKS. THE UPPER CONTROL ARMS ATTACHED WITH CADMIUM COATED NUTS CAN CAUSE THE BOLTS TO STRETCH DUE TO THE APPLICATION OF A HIGHER THAN SPECIFIED CLAMP LOAD. BREAKAGE OF THE UPPER CONTROL ARM FASTENERS COULD CAUSE THE AXLE TO ROTATE FORWARD UNDER BRAKING CONDITIONS.
Safety Risk
THIS ROTATION COULD TWIST THE STEERING LINKAGE AND POSSIBLY SEPARATE THE BRAKE LINES, INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL REPLACE THE UPPER CONTROL ARM BOLTS AND NUTS.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. ONE OF TWO BRACKETS USED TO BOLT THE FRONT SUSPENSION CONTROL ARM IN FRONT OF THE VEHICLE TO THE BODY STRUCTURE MAY NOT HAVE BEEN WELDED SUFFICIENTLY.
Safety Risk
THE CONTROL ARM COULD GRADUALLY LOOSEN AND ULTIMATELY SEPARATE FROM ITS BRACKET IN NORMAL DRIVING WHICH COULD CAUSE THE VEHICLE TO BE DIFFICULT TO CONTROL OR RESULT IN LOSS OF CONTROL. AS THE BRACKET LOOSENS, LOUD METALLIC KNOCKING SOUNDS IN FROM THE VEHICLE WILL BE HEARD.
Remedy
DEALERS WILL INSPECT THE BRACKET AND IF THE WELDING IS INSUFFICIENT, WILL REPLACE THE CONTROL ARM.
THE BOLTS THAT ATTACH THE FRONT UPPER CONTROL ARMS TO THE FRAME MOUNTING BRACKETS CAN LOOSEN AND FRACTURE AT ONE OF THE BOLT HOLES CAUSING SUBSTANTIAL NEGATIVE CAMBER AND STEERING PULL TO THE AFFECTED SIDE.
Safety Risk
IF THE DRIVER'S SIDE BRACKET FRACTURED AT BOTH BOLT HOLES, THE STEERING CONTROL ARM CAN CONTACT THE STEERING COLUMN SHAFT AND RESULT IN A LOSS OF STEERING CONTROL INCREASING THE POTENTIAL FOR AN ACCIDENT.
Remedy
DEALERS WILL INSPECT THE TORQUE LEVELS OF THE FOUR UPPER CONTROL ARM MOUNTING BOLTS, AND IF ANY ARE LOOSE, THE BRACKETS WILL BE INSPECTED FOR DAMAGE. IF DAMAGE IS PRESENT, IT WILL BE REPAIRED.
