Rear axles are considered lubricated for life when the vehicle is used for
normal service. See your scheduled maintenance guide for Severe Duty
requirements.
Traction-Lok axles use 2.1-2.3L (4.50-4.75 pints) of rear axle lubricant.
Add 118 ml (4 oz.) of Additive Friction Modifier XL-3 or equivalent
meeting Ford specification EST-M2C118–A for complete refill of
Traction-Lok rear axle.
Service refill capacities are determined by filling the rear axle 6 mm to
14 mm (1/4 inch to 9/16 inch) below the bottom of the filler hole.

Use of sythetic or sythetic blend motor oil is not mandatory. Engine oil
need only meet the requirements of Ford specification WSS-M2C153–H
and the API Certification mark.
