Recall 91V020700: Height Sensor Link Defect

THE LINK CONNECTING THE ELECTRONIC REAR HEIGHT SENSOR TO THE REAR AXLE CAN DISCONNECT UNDER SEVERAL CONDITIONS, ALLOWING THE ARM ATTACHED TO THE SENSOR TO LODGE BETWEEN THE REAR AXLE ASSEMBLY AND THE RIGHT REAR BRAKE PIPE. THIS ABRADES THE BRAKE PIPE AND COULD LEAD TO REAR BRAKE FAILURE. ABRASION OF THE BRAKE LINE COULD RESULT IN LOSS OF REAR BRAKES. THE FRONT BRAKES WOULD FUNCTION, BUT THE VEHICLE WOULD NEED INCREASED STOPPING DISTANCES WHICH COULD RESULT IN AN ACCIDENT. INSTALL RETENTION CLIPS TO INSURE THE LOWER AND UPPER BALL SOCKET CANNOT BE REMOVED FROM THE BALL; ADD A DOWN STOP ON THE SENSOR ARM; AND ADD A SHIELD ON THE REAR AXLE.

SYSTEM: BRAKES AND ELECTRONIC LEVEL CONTROL.

VEHICLE DESCRIPTION: MULTI-PURPOSE VEHICLES BUILT IN STAGES.

1992 GMC TYPHOON
