1990 Mack Mr Recall

THE STEERING ARMS ON THESE VEHICLES COULD DEVELOP CRACKS WHICH COULD PROLIFERATE AND EVENTUALLY CAUSE THE ARM TO BREAK WITHOUT WARNING. WHEN MANUFACTURED THESE LEVERS WERE NOT PEENED OR SHOT PEENING WAS INADEQUATE THEREBY ADVERSELY AFFECTING THE COMPRESSIVE STRESS LEVEL OF THE PART. CORRECTION: STEERING LEVERS WILL BE REPLACED WITH IMPROVED STEERING LEVERS WITH INCREASED FATIGUE STRENGTH.
