Maintenance and Specifications 3 4 Add the coolant type originally equipped in your vehicle. Your vehicle's rear axle is filled with a synthetic rear axle lubricant and is considered lubricated for life. These lubricants are not to be checked or changed unless a leak is suspected, service is required or the axle has been submerged in water. The axle lubricant should be changed any time the axle has been submerged in water. Service refill capacities are determined by filling the rear axle 9mm to 12mm (3/8 inch to 1/2 inch) below the bottom of the filler hole. 5 Add 118 ml (4 oz.) of Additive Friction Modifier XL-3 or equivalent meeting Ford specification EST-M2C118-A for complete refill of Limited Slip axles.
