CONDITION:

SOME OWNERS MAY COMMENT ON A SQUAWK NOISE COMING FROM THE FRONT SUSPENSION DURING LARGE SUSPENSION TRAVEL (I.E., GOING THROUGH A DIP). THIS CONDITION IS MOST NOTICEABLE IN COLD TEMPERATURES AND MAY OCCUR ON ONLY THE FIRST FEW JOUNCES AFTER A COLD SOAK.

CAUSE:

THIS CONDITION IS CAUSED BY THE STABILIZER SHAFT ROTATING WITHIN THE STABILIZER SHAFT INSULATOR.

CORRECTION:

REPLACE THE STABILIZER SHAFT INSULATOR WITH THE NEW SERVICE PART THAT IS MADE FROM A DIFFERENT RUBBER COMPOUND. REFER TO THE SERVICE PARTS IDENTIFICATION LABEL FOR SUSPENSION OPTION CODE (FE1, FE2, OR FE3). THE INSULATORS SHOULD BE INSTALLED PER SERVICE INFORMATION MANUAL PROCEDURES WITH THE SLIT TOWARD THE REAR OF THE CAR.
