Add 8 oz. (236 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford
Specification EST-M2C118– A for complete refill of limited slip Ford axles. Ford design
rear axles contain a synthetic lubricant that does not require changing unless you submerge
the axle in water.
2 Ford recommends using Motorcraft (Ford) DOT 3 LV High Performance Motor Vehicle
Brake Fluid, Motorcraft (Ford) DOT 4 LV High Performance Motor Vehicle Brake Fluid or
equivalent meeting WSS-M6C65-A1 or WSS-M6C65-A2. Use of any fluid other than the
recommended fluid may cause degraded brake performance and not meet the Ford
performance standards. Keep brake fluid clean and dry. Contamination with dirt, water,
petroleum products or other materials may result in brake system damage and possible
failure.

indicated on the dipstick blade or the dipstick handle. Check the container to verify the
fluid you are adding is of the correct type. Refer to your scheduled maintenance information
to determine the correct service interval.
Note: Automatic transmissions that require MERCON LV should only use MERCON LV fluid.
Use of any fluid other than the recommended fluid may cause transmission damage.
8 Indicates only approximate dry-fill capacity. Some applications may vary based on cooler
size and if equipped with an in-tank cooler. You should set the amount of transmission
fluid and fluid level by the indication on the dipstick’ s normal operating range.
