Lear Siegler Suspension recall
Recalled November 3, 1977 · NHTSA recall 77E024000 · Lear Siegler
Description
PIVOT CONNECTION LOCK NUTS ON THE INVOLVED SUSPENSION SYSTEMS MAY NOT HAVE BEEN PROPERLY TIGHTENED. THE NUT COULD FALL OFF THE BOLT IF NOT RETORQUED AFTER A SHORT PERIOD OF TIME IN SERVICE. THE BOLT HEAD CAN THEN MOVE OUT OF POSITION FAR ENOUGH TO MAKE CONTACT WITH THE EDGE OF THE TREAD ON THE INSIDE DUAL TIRE, WHICH CAN DESTROY THE TIRE. HOWEVER, IF THE PIVOT BOLT WAS INCORRECTLY INSTALLED WITH THE BOLT HEAD AWAY FROM THE TIRE, IT MAY FALL OUT, ALLOWING THE EQUALIZING BEAM TO SEPARATE FROM THE FRAME BRACKET. IF OTHER SUSPENSION COMPONENTS, SUCH AS THE AXLE CONNECTION, ARE WORN AND NOT MAINTAINED, LOSS OF THE PIVOT BOLT WILL LEAD TO VEHICLE INSTABILITY.
What to do
DEALER WILL INSTALL REPLACEMENT LOCK NUTS AND TIGHTEN THEM TO THE PROPER SPECIFICATIONS WITHOUT CHARGE.
