DRIVELINE UNIVERSAL JOINT, DRIVESHAFT AND SLIP YOKE
WARNING: Turn off the power running boards, if equipped,
before working under the vehicle, jacking or placing any object
under the vehicle. Never place your hand between the extended
running board and the vehicle. A moving running board may cause
injury.
If the original universal joints are replaced with universal joints equipped
with grease fittings, periodic lubrication will be necessary.
Note: Your vehicle’s driveshaft is balanced. If undercoating the vehicle,
protect the driveshaft, universal joints, and axle and transmission flanges
to prevent overspray of any undercoating material. If your vehicle has
four-wheel drive, your vehicle has two driveshafts, one connected to the
rear axle and one connected to the front axle.
AIR FILTER
Refer to scheduled maintenance information for the appropriate
intervals for changing the air filter element.
When changing the air filter element, use only the air filter element
listed. Refer to Motorcraft part numbers in this chapter.
WARNING: To reduce the risk of vehicle damage and/or
personal burn injuries do not start your engine with the air
cleaner removed and do not remove it while the engine is running.
