2000 Ford Expedition Differential Cover Parts Q&A

• Q: How to service and repair the 8.8-inch ring gear differential cover on 2000 Ford Expedition?

  A: The process of servicing or repairing the 8.8-inch ring gear differential cover requires users to disable air suspension electrical power by switching off the air suspension switch in the right-hand kick panel area to avoid unexpected air spring inflation or deflation during vehicle hoisting, jacking, or towing. The vehicle needs to be elevated while support is applied before draining lubricant into a clean container for further use by removing both the differential housing cover and the 10 bolts. You must first wipe all machined surfaces of the differential housing and cover with oil-free cloths while using protective covers to shield the axle interior from contaminants. A continuous bead of Clear Silicone Rubber F7AZ-19554-CA along with an equivalent sealant fulfilling Ford specification ESB-M4G92-A should be applied to the differential housing cover mounting area. Install the cover within 15 minutes of sealant application. The sealant needs to cure for one hour before reinstalling the differential housing cover by using the provided 10 bolts to secure it. The Traction-Lok axles require 118 ml (4 oz) of Additive Friction Modifier C8AZ-19B546-A or its equivalent per Ford EST-M2C118-A specification followed by 2.5 - 2.6 liters (5.25 - 5.50 pints) of SAE 75W-140 High Performance Rear Axle Lubricant F1TZ-19580-B or its Ford WSL-M2C192-A equivalent before installing the filler plug. This lubrication process needs to be at a service refill capacity of 6.4 - 14.3 mm Processing vehicles with air suspension requires activating the system following which the vehicle should be lowered.
