2001 Freightliner Business Class recalls

ON CERTAIN HEAVY DUTY TRUCKS EQUIPPED WITH MERITOR WABCO PNEUMATIC ANITLOCK BRAKE SYSTEM (ABS) VALVE PACKAGES, THE ASSEMBLY BOLTS ON THESE VALVE PACKAGES WERE NOT TIGHTENED CORRECTLY.

BOLTS TORQUED BELOW SPECIFICATION WILL NOT RELIABLY PREVENT AIR LEAKAGE AT THE AFFECTED ABS VALVE PACKAGE INTERFACE JOINTS ONCE THE COMPONENT BEGINS NORMAL VEHICLE OPERATION. IF AIR LEAKS DEVELOP AT ANY OF THE ABS VALVE PACKAGE INTERFACE JOINTS, BRAKE SYSTEM PRESSURE REDUCTIONS COULD OCCUR DURING BRAKING OR NORMAL OPERATION WITH UNITS EQUIPPED WITH THE TRACTION CONTROL OPTION, POTENTIALLY EXTENDING STOPPING DISTANCES, POSSIBLY RESULTING IN A VEHICLE CRASH.

DEALERS WILL TIGHTEN THE FASTENERS TO THE PROPER SPECIFICATION. OWNER NOTIFICATION BEGAN APRIL 4, 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 FREIGHTLINER AT 1-800-547-0712.

VEHICLE DESCRIPTION: VEHICLES EQUIPPED WITH CERTAIN HALDEX BRAKE SYSTEM TWO AND FOUR PORT RELAY VALVES. THE VALVE MAY STICK OPEN WHEN A HIGH-PRESSURE APPLICATION IS RELEASED.

WHEN THE VALVE STICKS OPEN, IT CAN RESULT IN A TOTAL LOSS OF AIR FROM EITHER THE SERVICE OR THE PARK BRAKE SYSTEM. THE DRIVER MAY LOSE BRAKING ABILITY UNDER A SERVICE APPLICATION, POSSIBLY RESULTING IN A VEHICLE CRASH.

DEALERS WILL REPLACE THESE VALVES. OWNER NOTIFICATION BEGAN OCTOBER 17, 2001. 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 FREIGHTLINER AT 1-800-547-0712.

ON CERTAIN TRUCKS EQUIPPED WITH MERITOR BRAND 12" X 4" DCM DRUM PARKING BRAKE, THE BOLTS USED TO ATTACH THE PARKING BRAKE ASSEMBLY TO THE FLANGE YOKE ARE TOO LARGE AND CAN INTERFERE WITH THE PROPER ENGAGEMENT OF THE BRAKING SYSTEM AND POSSIBLY DISENGAGE.

IMPROPER ENGAGEMENT OF THE PARKING BRAKE COULD RESULT IN THE VEHICLE ROLLING AWAY WITHOUT PRIOR WARNING POSSIBLY RESULTING IN PERSONAL INJURY OR DEATH.

DEALERS WILL REPLACE THE ATTACHING BOLTS WITH THE CORRECT SIZE BOLTS FREE OF CHARGE. OWNER NOTIFICATION IS EXPECTED TO BEGIN DURING OCTOBER 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 FREIGHTLINER AT 1-800-547-0712.

ON CERTAIN TRUCKS EQUIPPED WITH TRUCK HUB UNITS MANUFACTURED BY SKF EXCLUSIVELY FOR USE ON ARVINMERITOR'S FF98X SERIES NON-DRIVE STEER AXLES, THE HUB UNIT BEARINGS CAN WEAR PREMATURELY.

SEIZURE OF THE BEARINGS CAN CAUSE WHEEL SEPARATION OR WHEEL END FIRE.

DEALERS WILL REPLACE BOTH FRONT HUBS. OWNER NOTIFICATION IS EXPECTED TO BEGIN ON OR BEFORE SEPTEMBER 20, 2003. 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 FREIGHTLINER AT 1-800-547-0712.

ON CERTAIN CREW CAB TRUCKS EQUIPPED WITH HYDRAULIC BRAKES, THE HYDRAULIC BRAKE LINES FROM THE CHASSIS MOUNTED ANTI-LOCK BRAKE SYSTEM (ABS) MODULATOR VALVE CAN BE DAMAGED BY INTERFERENCE WITH THE CAB MOUNTED AUXILIARY HEATER DUCT.

THIS COULD RESULT IN EXTENDED BRAKING DISTANCE, INCREASING THE RISK OF A CRASH.

DEALERS WILL REPLACE THE BRAKE LINES. OWNER NOTIFICATION BEGAN ON DECEMBER 26, 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 FREIGHTLINER AT 1-800-547-0712.

VEHICLE DESCRIPTION: MEDIUM DUTY TRUCKS, FIRE TRUCKS, AND TRANSIT BUSES AND SCHOOL BUSES EQUIPPED WITH ELECTRONIC THROTTLE CONTROL/ACCELERATOR PEDALS SUPPLIED BY WILLIAMS CONTROLS INDUSTRIES. THE WELD ATTACHING THE CLEVIS TO THE PLATE HAS INSUFFICIENT PENETRATION AND COULD ALLOW THE CLEVIS TO SEPARATE FROM THE PLATE.

IF THE CLEVIS SEPARATED FROM THE PLATE WHILE THE VEHICLE WAS IN USE, THE VEHICLE WOULD RETURN TO IDLE, INCREASING THE RISK OF A CRASH.

DEALERS WILL REPLACE THESE PEDALS. OWNER NOTIFICATION BEGAN MARCH 18, 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 FREIGHTLINER AT 1-800-547-0712.
