VEHICLE DESCRIPTION: CLASS 8 TRUCKS EQUIPPED WITH FELSTED ELECTRONIC ACCELERATOR PEDALS. THE RETURN SPRINGS CAN BREAK ON THE ACCELERATOR PEDALS THAT ARE EQUIPPED WITH STAINLESS STEEL OR ELECTROPLATED WIRE RETURN SPRINGS.

Consequence: THIS CONDITION COULD CAUSE THE PEDAL TO GO TO FULL THROTTLE IF BOTH RETURN SPRINGS BREAK, INCREASING THE RISK OF A CRASH.

Consequence: THIS CAN LEAD TO PREMATURE WEAR WITH POSSIBLE SEPARATION OF THE BALL STUD FROM THE SOCKET, INCREASING THE RISK OF LOSS OF CONTROL OF THE VEHICLE.

Remedy: DEALERS WILL REMOVE AND REPLACE ALL AFFECTED TIE RODS AND DRAG LINKS WITH DIFFERENT DESIGNED ENDS. TRUCKS THAT HAVE BEEN REPAIRED UNDER RECALL 00V246103/SC0262 WILL NOT BE RE-RECALLED.

ON CERTAIN CLASS 8 HEAVY DUTY TRUCKS EQUIPPED WITH R. H. SHEPPARD M90 STEERING GEARS, AN INCORRECT HOSE WAS USED FOR THE HIGH-PRESSURE LINE BETWEEN THE POWER STEERING PUMP AND THE STEERING GEAR. THE HOSE IS RATED AT 2000 PSI, WHILE IT SHOULD BE RATED AT 3000 PSI.
