  Q: What steps should be taken before beginning the differential cover service to ensure safety and proper procedure on Ford Crown Victoria?

  A: The service for differential covers must start with turning off the Air Suspension system electrical power through the RH kick panel mounted air suspension switch to stop any unwanted air spring inflation or deflation. Remove the differential housing bolts to drain out lubricant from the differential housing while you support the vehicle through a well-cleaned storage container for the later reuse of lubricant. Wash all machined areas on both the differential housing and cover before protecting the rear axle interior from foreign particles. Apply Clear Silicone Rubber F7AZ-19554-CA sealant extending as a single bead to differential housing cover before immediate installation within 15 minutes to prevent new sealant usage. The silicone sealant needs one hour of curing time before filling the axle with lubricating fluid. The process starts with adding 118 ml (4 oz.) of Additive Friction Modifier C8AZ-19B546-A which meets Ford specification EST-M2C118-A to the Traction-Lok axles before proceeding to fill them with 1.8 liters (3.75 pints) of SAE 80W-90 Premium Rear Axle Lubricant XY-80W90-QL which has Ford specification WSP-M2C197-A. Reactivate the air suspension system before executing the vehicle lowering procedure when your vehicle is equipped with this system.
