Mack MH: Steering

Affects Mack MH · 1987 — about 0 vehicles.

The hazard

VEHICLES WITH SHEPPARD STEERING GEAR WERE MANUFACTURED WITH AN INCORRECT PITMAN ARM TO DRAG LINK ANGLE DUE TO A MISPLACED PITMAN ARM TIMING MARK. IN A FULL RIGHT HAND TURN WITH THE LEFT HAND WHEEL UNSUPPORTED, THE STEERING LINKAGE COULD GO INTO A TOGGLE CONDITION RESULTING IN A SLOW WHEEL RETURN. THIS COULD IMPAIR STEERING CONTROL AND POSSIBLY LEAD TO A VEHICLE CRASH WITHOUT PRIOR WARNING. MISMARKED PITMAN ARMS WILL BE REPLACED. NOTE: NO VEHICLES LOCATED IN CANADA. 24-06-88.
