TSB 20-23072020-11-05. Service bulletin. ELECTRICAL SYSTEM; WHEELS; EQUIPMENT. Some 2003-2020 Expedition/Navigator and 2006-2020 F-150 vehicles equipped with TOD transfer cases may exhibit grinding/clicking/ratcheting noise from the front wheel area. This may be due to partial engagement of the integrated wheel ends (IWE). To correct this condition, follow the Service Procedure steps to remove and cap the vacuum supply line.
SSM 465422017-08-01. Service bulletin. ELECTRICAL SYSTEM. When ordering a 2005 to 2008 remanufactured 5.4L 3v or 6.8L 3v engine, spark plug boots may be provided in the packaging. Replace all black spark plug boots from the original engine with the 'brown' spark plug boots, as provided. The updated 'brown' spark plug boots are longer than the black boots to accommodate a running change in the spark plug length. The ignition coil bodies and spring/resistor are transferable and only the rubber boots require replacement. Failure to install the spark plug boots provided with the replacement engine could lead to drivability concerns.
