Fuel system, other:storage:tank assembly:pressure relief devices
Problem: On certain chassis built with lng engines, the nexgen lng tank's primary and secondary relief valves could fail to open and relieve tank pressure.
Risk: This could cause ice buildup on the discharge side of the primary and secondary pressure system allowing the relief system to freeze and become blocked resulting in over pressurization of the lng tanks creating the risk of catastrophic tank rupture which could cause serious injury or death.
Fix: Dealers will retrofit the lng tanks with a new primary relief valve pipe away tube and a new ventilated shroud. The recall began april 6, 2004. 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 mack at 1-610-709-3337.

Problem: Vehicle description: heavy duty trucks equipped with tie rod assemblies containing 24-dl model ball sockets and manufactured by trw. Certain of the tie rod ball-socket bearings have a below-specification case depth and/or hardness, which can lead to premature wear of the socket.

Risk: This condition could cause the pedal to go to full throttle if both return springs break, increasing the risk of a crash.
Fix: Replacement accelerator pedals equipped with return springs manufactured of music wire with one additional coil on each spring and with an organic coating, eliminating electroplating will be installed.
Service brakes, air:antilock
Problem: Vehicle description: heavy duty trucks 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.
Risk: 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.
Fix: Dealers will replace the abs ecu.
