Mack Trucks, Inc.
The problem
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.
Risk
THIS HOSE COULD DEVELOP A LEAK OR BURST WHILE IN SERVICE. SHOULD THE LINE BURST, STEERING CONTROL WOULD STILL BE MAINTAINED, BUT A LOSS OF POWER ASSIST WILL BE EXPERIENCED.
What owners should do
DEALERS WILL REPLACE THE STEERING HOSE. OWNER NOTIFICATION BEGAN MARCH 22, 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 MACK AT 1-610-709-3011.
