AS A RESULT OF SEVERE SHOCK AND VIBRATIONS, THE BRAKE SPIDERS ON THE INVOLVED VEHICLES MAY DEVELOP CRACKS NEAR THE CAMSHAFT MOUNTING BOSS. THE CRACK PROPAGATES ACROSS THE SPIDER UNTIL THE CAMSHAFT BOSS IS COMPLETELY SEVERED FROM THE REMAINDER OF THE SPIDER. WHEN THE CAMSHAFT BOSS HAS COMPLETELY SEVERED, THE S-CAM, S-CAM BRACKET, AIR CHAMBER AND SLACK ADJUSTER CAN FALL AWAY FROM THE BRAKE SPIDER RESULTING IN A "NO BRAKE" CONDITION ON THE WHEEL.
Consequence & remedy
Consequence: Not supplied
Remedy: THE DEALER WILL REPLACE THE FRONT BRAKE SPIDERS ON ALL AFFECTED VEHICLES USED IN SNOW PLOW DUMP AND REFUSE HAULING APPLICATIONS. THIS WILL BE DONE AT NO CHARGE.
THE DEFICIENCY EXISTS IN THE FRONT AXLE FORGED ALUMINUM HUBS. THE DEFICIENCY WHICH IS IN THE BARREL SECTION BETWEEN THE INNER AND OUTER BEARING, MAY RESULT IN CRACKS WHICH COULD LEAD TO HUB FAILURE. WHEN HUB FAILURE OCCURS, THE SEPARATED HUB IS RETAINED ON THE AXLE SPINDLE BY THE WHEEL BEARING AND ADJUSTING NUT.
Consequence & remedy
Consequence: Not supplied
Remedy: THE DEALER WILL REPLACE THE FORGED ALUMINUM HUBS WITH STEEL HUBS, AT NO CHARGE.
ON THE INVOLVED VEHICLES, THE HOSE USED TO SUPPLY VACUUM TO THE BRAKE POWER UNIT OR VACUUM RESERVE TANK MAY HAVE BEEN OF THE WRONG MATERIAL. THIS HOSE COULD DEFORM SUFFICIENTLY DURING NORMAL OPERATION TO CAUSE A REDUCTION IN VACUUM ASSIST TO THE BRAKE POWER UNIT. THIS WOULD RESULT IN GREATER BRAKE PEDAL EFFORT BY OPERATOR AND AN INCREASE IN VEHICLE STOPPING DISTANCES.
Consequence & remedy
Consequence: Not supplied
Remedy: THE DEALER WILL INSPECT AND, IF NECESSARY, REMOVE INCORRECT HOSE AND INSTALL THE PROPER VACUUM HOSE.
