78V172000 · Steering:Linkages:Knuckle:Spindle:Arm
Reported: 1978-08-08 (August 8, 1978)
THE EXISTING CROSS STEERING ARMS MAY HAVE INSUFFICIENT FATIGUE LIFE IN THE NECK AREA. THIS IS NEAR THE BOSS FOR THE CROSS STEERING TUBE BALL JOINT CONNECTION. FAILURE OF EITHER OF THE CROSS STEERING LEVERS COULD LEAD TO LOSS OF STEERING CONTROL OF THE RIGHT FRONT WHEEL.
Remedy: THE DEALER WILL INSPECT AND, IF NECESSARY, INSTALL CROSS STEERING ARMS OF IMPROVED DESIGN AND GREATER STRENGTH.
NHTSA campaign record ↗81V154000 · Steering: Steering Wheel/Handle Bar
Reported: 1981-12-29 (December 29, 1981)
THE FLOORBOARD OPENING AND THE STEERING COLUMN SEAL BRACKET MAY NOT ALLOW SUFFICIENT CLEARANCE FOR THE SHAFT TO TURN FREELY IN THE CENTER OF THE BRACKET/SEAL. THE PINCH BOLT IN THE COLUMN YOKE MAY BIND OR LOCK THE COLUMN AGAINST THE BRACKET, ALLOWING LITTLE OR NO WHEEL RETURN.
Remedy: DEALER WILL ENLARGE THE HOLE IN THE FLOORBOARD TO PROVIDE CLEARANCE FOR THE STEERING COLUMN U-JOINT PINCH BOLT. A NEW BRACKET AND CLAMP WILL ALSO BE INSTALLED WITHOUT CHARGE TO OWNER.
NHTSA campaign record ↗83V037000 · Steering: Steering Wheel/Handle Bar
Reported: 1983-04-05 (April 5, 1983)
ON THE INVOLVED VEHICLES THE FLOORBOARD OPENING AND THE STEERING COLUMN SEAL BRACKET DO NOT HAVE SUFFICIENT CLEARANCE TO ALLOW THE SHAFT TO TURN FREELY. THIS CAUSES THE PINCH BOLT TO BIND OR LOCK AGAINST THE SEAL BRACKET.
Remedy: THE HOLE IN THE FLOORBOARD WILL BE ENLARGED TO ALLOW SUFFICIENT CLEARANCE OF THE STEERING COLUMN U-JOINT PINCH BOLT, AND A NEW BRACKET AND LAMP WILL BE INSTALLED AT NO CHARGE TO OWNER.
NHTSA campaign record ↗84V036000 · Suspension:Rear:Springs:Leaf Spring Assembly
Reported: 1984-03-23 (March 23, 1984)
SPRING SEAT CAN DEFORM, WHICH CAUSES A DECREASE IN THE CLAMPING FORCE IN THE SUSPENSION ASSEMBLY. LOSS OF CLAMPING FORCE MAY BRING ABOUT AXLE MISALIGNMENT OR AXLE HOUSING FAILURE.
Remedy: THE AXLE HOUSING WILL BE INSPECTED AND REPLACED, IF NECESSARY. THE SPRING SEATS WILL ALSO BE REPLACED.
NHTSA campaign record ↗85V157000 · Steering: Steering Wheel/Handle Bar
Reported: 1985-11-26 (November 26, 1985)
THE SPLINED STEERING SHAFT MAY NOT BE SUFFICIENTLY ENGAGED AS DESIGNED DUE TO INACCURATE DRILLING OF THE HOLES IN THE FRAME TO WHICH THE CAB FRONT MOUNT MEMBER IS BOLTED. UNDER CERTAIN CONDITIONS THE STEERING SHAFT MAY DISENGAGE. CONSEQUENCE OF DEFECT: A JARRING IMPACT MIGHT CAUSE DISENGAMENT OF THE SPLINED SHAFT RESULTING IN LOSS OF STEERING CONTROL AND POSSIBLY AN ACCIDENT.
Remedy: REPLACE SHAFTS WHICH MEASURE UNDER THE MINIMUM ENGAGEMENT DIMENSIONS WITH LONGER SHAFT.
NHTSA campaign record ↗91V070000 · Steering:Linkages
Reported: 1991-05-01 (May 1, 1991)
STRESSES IMPOSED ON THE LEVER DURING TURNING MANEUVERS AND/OR IMPACT INCIDENTS, SUCH AS WOULD BE CAUSED BY CURBS OR ROAD SURFACE IRREGULARITY, REDUCE THE LIFE EXPECTANCY OF THE PART. THE STEERING LEVER MAY CRACK AND EVENTUALLY THE STRESSES COULD CAUSE THE STEERING LEVER TO BREAK.
Consequence: A BROKEN STEERING LEVER WILL CAUSE LOSS OF STEERINGCONTROL WITHOUT PRIOR WARNING WHICH MAY RESULT IN A VEHICLE CRASH.
Remedy: REPLACE THE DEFECTIVE STEERING ARMS.
