Recalls
3 campaigns cover the 4900EX.
DAIMLER TRUCKS IS RECALLING 7 MY 2006-2007 WESTERN STAR 4900EX TRUCKS FOR FAILING TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, 'LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT.' ADDITIONAL MARKER LAMPS WERE INSTALLED BETWEEN THE REQUIRED IDENTIFICATION LAMPS AND CLEARANCE LAMPS ON THE TOP OF SOME TRUCK CABS.
ON CERTAIN VEHICLES, THERE IS A DEFECT IN THE INTERAXLE DRIVELINE YOKES. THE BOLT HOLES LOCATED ON THE EARWORK OF THE MALE SHAFT YOKES WERE MANUFACTURED WITH AN OVERSIZED MINOR THREAD DIAMETER.
ON CERTAIN TRUCKS AND TRUCK-TRACTORS EQUIPPED WITH TRW DRAG LINK ASSEMBLIES, THE REPLACEMENT CLAMP AND DRAG LINK ASSEMBLIES CONTAIN A POTENTIALLY DEFECTIVE 5/8-11-GRADE B PREVAILING TORQUE HEX NUT. IF THE FINAL TIGHTENING IS LESS THAN 65 LB.-FT., THE CLAMP LOAD WOULD BE UNACCEPTABLY LOW AND COULD COMPROMISE THE INTEGRITY OF THE DRAG LINK.
