Vehicle speed control

NHTSA recall 95V143000 · Aug 2, 1995 · 29,000 vehicles

Problem: THE HAND THROTTLE CABLE CAN WEAR THE BRASS SWIVEL BLOCK ON THE GOVERNOR LEVER THROUGH WHICH IT PASSES.

Risk: THIS WEAR CAN RESULT IN THE GOVERNOR JAMMING IN THEDAMAGED SWIVEL AND COULD PREVENT THE GOVERNOR LEVER FROM RETURNING TO THE IDLE POSITION.

Fix: DEALERS WILL INSTALL A REVISED GOVERNOR LEVER WITH A STAINLESS STEEL SWIVEL. ALSO LETTERS WILL BE SENT TO VEHICLE OWNERS THAT HAVE THE SAME VEHICLES BUT DO NOT HAVE A FORD INSTALLED HAND THROTTLE ADVISING THEM THAT THEY MAY REQUIRE SERVICE IF THEY HAVE HAD AN AFTER MARKET HAND THROTTLE INSTALLED.

Steering › Rack and pinion

NHTSA recall 94V118000 · Jun 27, 1994 · 12,700 vehicles · opened after NHTSA action (ODI)

Problem: THE STEERING GEARS HAVE AN IMPROPERLY MACHINED SNAP RING GROOVE. THIS CAN CAUSE A FRACTURE OF THE SNAP RING WITH SUBSEQUENT DAMAGE TO THE RECIRCULATING BALL GUIDE TUBE. ALSO, THE O-RING SEAL IN VEHICLES BUILT AFTER FEBRUARY 1988 DOES NOT MEET SPECIFICATIONS AND IS INADEQUATE, CAUSING INTERIOR LEAKAGE AROUND THE O-RING / GLIDE RING SEAL IN THE STEERING GEAR.

Risk: THE FRACTURE OF THE SNAP RING RESULTS IN INCREASING DETERIORATION OF THE ABILITY TO TURN THE VEHICLE TO THE RIGHT. THE DRIVER WOULD EXPERIENCE INCREASED STEERING EFFORTS OR A "CRUNCHY" FEELING AT THE STEERING WHEEL. THE INADEQUATE O-RING SEAL CAUSES MOMENTARY REDUCTIONS IN POWER STEERING ASSIST AT LOW SPEED AND CERTAIN LEFT TURN MANEUVERS. BOTH CONDITIONS RESULT IN DECREASED STEERING ABILITY.

Fix: DEALERS WILL REBUILD THE STEERING GEAR. IF A BROKEN SNAP RING IS FOUND DURING REBUILDING, THE STEERING GEAR WILL BE REPLACED WITH A REMANUFACTURED UNIT.
