FORD 2007 Explorer Sport Trac v.2 - Manual (Page 309)

DRIVELINE UNIVERSAL JOINT AND SLIP YOKE
If the original universal joints are replaced with universal joints equipped
with grease fittings, lubrication will be necessary.
Note: Your vehicle’s driveshaft is balanced. If undercoating the vehicle,
protect the driveshaft and universal joints to prevent overspray of any
undercoating material.
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 Motorcraft air filter
element listed. Refer to Motorcraft part numbers in this chapter.
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.
Changing the air filter element
1. Release the clamps that secure the air filter housing cover.
2. Carefully separate the two halves of the air filter housing.
3. Remove the air filter element from the air filter housing.
4. Wipe the air filter housing and cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be careful not to crimp the filter
element edges between the air filter housing and cover. This could cause
filter damage and allow unfiltered air to enter the engine if not properly
seated.
6. Replace the air filter housing cover and secure the clamps.
Note: Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
