1998 Sterling Acterra recalls

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH HYDRAULIC BRAKES AND A DURAPARK PARK BRAKE SYSTEM MANUFACTURED BY ARVINMERITOR. AIR IS ENTERING THE HYDRAULIC REAR BRAKE CYLINDERS THROUGH AN UNKNOWN PATH AND THE REAR SELF-ADJUSTING BRAKES MAY NOT BE OPERATING PROPERLY.

THIS RESULTS IN SPONGY OR SOFT FEEL TO THE BRAKE PEDAL AND A LOSS OF REAR BRAKING CAPABILITY.

DEALERS WILL REMOVE AND REPLACE THE ABS ECU AND INSPECT THE BRAKE PEDAL FOR PROPER TRAVEL. IF EXCESSIVE TRAVEL IS DETECTED, THE BRAKE SYSTEM WILL BE BLED AND REAR BRAKES ADJUSTED. AS AN INTERIM MEASURE, FREIGHTLINER WILL NOTIFY ALL OWNERS TO HAVE THEIR VEHICLES INSPECTED TO ASSURE PROPER FUNCTION OF THE BRAKE SYSTEM. THIS WILL INCLUDE ADJUSTING AND BLEEDING THE BRAKES. ALSO, OWNERS WILL BE INSTRUCTED THAT ON A REGULAR BASIS THEY SHOULD DO SEVERAL HARD BRAKE APPLICATIONS WHILE STOPPED. THIS WILL EXERCISE THE SELF-ADJUSTING SYSTEM AND IF THEY OBSERVE A LOW OR SPONGY BRAKE PEDAL THEY WILL BE INSTRUCTED TO TAKE THEIR VEHICLE IN FOR ADDITIONAL SERVICE. OWNER NOTIFICATION BEGAN MARCH 21, 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 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.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS AND SCHOOL BUS CHASSIS BUILT WITH BENDIX AIR ABS WITH AN EC-17 1030R ELECTRONIC CONTROL UNIT (ECU), THERE HAVE BEEN REPORTS OF UNWANTED ABS ACTIVATION AT LOW SPEEDS CAUSED BY 1) CHAFED ABS WHEEL SPEED SENSOR WIRES ON ROTATING PARTS OR 2) A DAMAGED COMPONENT AT THE WHEEL END THAT GENERATES A CERTAIN TYPE OF ERRATIC SENSOR SIGNAL.

THIS CONDITION COULD CAUSE THE ABS ECU TO EXHAUST THE AIR AT THE AIR BRAKE MODULATORS FOR ONE OR MORE OF THE WHEELS. THIS COULD RESULT IN EXTENDED BRAKING DISTANCES AND A POSSIBLE CRASH.

DEALERS WILL REPLACE THE ABS ECU.
