Recall history
5 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
78V139000 · Engine And Engine Cooling:Cooling System:Fan
Reported: 1978-06-13 (June 13, 1978)
THE HUB PORTION OF THE FAN BLADE ASSEMBLY COULD CRACK DUE TO HIGH STRESS LEVELS GENERATED DURING ENGINE OPERATING CONDITIONS. EVENTUALLY, THE BLADE COULD BREAK APART AT THE HUB AND BLADE PIECES COULD BE PROPELLED INTO THE ENGINE. IF THE HOOD IS OPEN WHILE THE ENGINE IS RUNNING, THE FRAGMENTS WOULD BE FREE TO FLY FROM THE VEHICLE.
Remedy: DEALER WILL REPLACE THE FAN BLADE ASSEMBLY WITHOUT CHARGE TO OWNER.
NHTSA campaign record ↗79V175000 · Suspension:Front:Wheel Bearing
Reported: 1979-07-23 (July 23, 1979)
UNDER CERTAIN DRIVING CONDITIONS, THESE VEHICLES CAN EXPERIENCE TEMPERATURES IN THE FRONT WHEEL OUTER BEARING AREA WHICH CAN AFFECT THE WHEEL BEARING GREASE. THIS CAN RESULT IN INADEQUATE LUBRICATION OF THE BEARING. THIS CONDITION MAY BE FURTHER AGGRAVATED BY IMPROPER ADJUSTMENT OF THE FRONT WHEEL SPINDLE NUT.
Remedy: THE DEALER WILL INSTALL NEW FRONT WHEEL OUTER BEARINGS PACKED WITH GREASE AND THE SPINDLE WILL BE COATED WITH LUBRICANT. NEW GREASE RETAINER CAPS WILL ALSO BE INSTALLED TO MAINTAIN GREASE IN OUTER BEARING. THIS WILL BE DONE FREE OF CHARGE.
NHTSA campaign record ↗81V025000 · Suspension:Rear
Reported: 1981-02-25 (February 25, 1981)
THE BOLTS THAT ATTACH THE LOWER REAR CONTROL ARM TO THE FRAME MAY FRACTURE. THE REAR CONTROL ARM SUPPORTS AND POSITIONS THE REAR AXLE. FRACTURE OF THE BOLTS WOULD ALLOW THE CONTROL ARM TO DROP FREE.
Remedy: BOTH REAR CONTROL ARM ATTACHMENT BOLTS WILL BE REPLACED WITHOUT CHARGE.
NHTSA campaign record ↗84V149000 · Power Train:Axle Assembly:Axle Shaft
Reported: 1984-11-24 (November 24, 1984)
REAR AXLE ASSEMBLY MAY HAVE AXLES THAT WERE IMPROPERLY MANUFACTURED. THIS CONDITION MAY RESULT IN SEPARATION OF THE AXLE SHAFT AND WHEEL ASSEMBLY FROM THE VEHICLE.
Remedy: THE DEALER WILL INSPECT THE REAR AXLE TO DETERMINE WHETHER IT WAS MANUFACTURED AT THE BUFFALO PLANT. IF SO, THEY WILL MAKE AXLE MEASUREMENTS AND IF NECESSARY REPLACE OR MODIFY AFFECTED AXLE COMPONENTS WITHOUT CHARGE.
NHTSA campaign record ↗85V048000 · Service Brakes, Hydraulic:Foundation Components:Drum:Wheel Cylinders
Reported: 1985-04-29 (April 29, 1985)
EXCESSIVE ENLARGEMENT OF THE WHEEL CYLINDER PILOT HOLE IN THE REAR BRAKE BACKING PLATE COULD ALLOW THE WHEEL CYLINDER TO ROTATE AND CAUSE LOSS OF BRAKE FLUID. CONSEQUENCE OF DEFECT: A LOSS OF BRAKE FLUID LEADS TO LOSS OF REAR BRAKE ACTION, CREATING THE POTENTIAL FOR AN ACCIDENT. FRONT BRAKES WOULD REMAIN OPERATIONAL.
Remedy: ADD A PART TO PREVENT WHEEL CYLINDER FROM ROTATING.
