These lubricants do not need to be checked or changed unless a leak is suspected, service is required or the axle assembly has been submerged in water. The axle lubricant should be changed any time the rear axle has been submerged in water. Service refill capacity is determined by filling the axle to 1/4-9/16 inch (6-14 mm) below the bottom of the filler hole with the vehicle on a level surface. Add 4 oz. (118 ml) of FEHP Friction Modifier, XL-7 or equivalent, for complete fill of 8.8 inch and 9.75 inch Traction-Lok axles. 7 Service refill capacity is determined by filling the axle to the bottom of the filler hole with the vehicle on a level surface. 6 For 10.25 inch Traction-Lok axles, use 6.5 pints (3.1L) of Motorcraft SAE 75W-90 Fuel Efficient High Performance Synthetic Rear Axle Lubricant and 4 oz. (118 ml) of FEHP Friction Modifier XL-7 or equivalent. Use of synthetic or synthetic blend motor oil is not mandatory.
