CERTAIN HEAVY DUTY CLASS 8 TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 120, "TIRE SELECTION AND RIMS FOR MOTOR VEHICLES OTHER THAN PASSENGER CARS." THE WEIGHT CERTIFICATION LABEL WHICH CONTAINS FRONT GROSS AXLE WEIGHT RATING (GAWR) INFORMATION DOES NOT ACCURATELY REFLECT THE ACTUAL FRONT GROSS AXLE WEIGHT.
Consequence & remedy
Consequence: WHEN OPERATING BOBTAIL WITH FULL FUEL TANKS AND TWO OCCUPANTS WITH AN ALLOWANCE FOR PERSONAL BELONGINGS, THE ACTUAL GROSS AXLE WEIGHT MAY EXCEED THE STATED RATING FOUND ON THE WEIGHT CERTIFICATION LABEL.
Remedy: DEALERS WILL INSTALL NEW FRONT STEER AXLE TIRES AND NEW CERTIFICATION LABEL STATING THE NEW FRONT STEER AXLE WEIGHT RATING. OWNER NOTIFICATION BEGAN DECEMBER 19, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT VOLVO TRUCKS AT 1-800-528-6586.
