How to service and repair the differential carrier on 2006 Ford F-250 Super Duty?

Question

Accepted Answer

A steam cleaning operation of the axle assembly should be the first step before differential carrier servicing to minimize premature wear caused by abrasive dust particles. Before starting the procedure you must engage the parking brake while placing wheel chocks in position to drain the axle lubricant into an appropriate container. You must drain the assembly after removing its bottom two carrier bolts. The service starts with the separation and safe relocation of driveshafts when equipped with rear anti-lock brake sensors. You should unscrew the pinion hex nut when required. When removing the axle shaft flange from the hub keep away from using steel hammers or sledges because this creates the risk of cracking and avoid prying and chiseling the axle shaft flange to protect the hub sealing area from damage. Take out all axle shafts and keep two top carrier housing bolts while noting their distance and locations before throwing away the differential carrier housing bolts. Fasten the carrier to a jack support and then take the carrier out of the housing before removal. Secure a proper jack underneath the carrier while removing and discarding the two top carrier-to-axle housing bolts. Afterward use the slots to move the carrier away from the axle housing by 25.4 - 50.8 mm (1 - 2 inches) before fully taking it off. The components need cleaning with either emulsion cleaners or petroleum-based solvents while receiving a light application of protective lubricant or rust inhibitor before storage in wax paper. Thoroughly inspect the gear set for pitting along with scoring and wear and damage and replace any necessary components. The inspection of splines must verify their condition from wear damage and distinguish any cracks or distortion while inspecting the axle flange O-ring. Wash the internal cavity of the axle housing along with sealing attachment areas and the carrier mounting bolt holes while repairing degenerated or broken threads that necessitate replacement. Obtain instructions for differential case and ring gear assembly before disassembling camber. Start by placing continuous sealant against the axle mounting flange and bolt holes before inserting two mounting studs through the housing while the carrier remains stationary. Use the studs for aligning the carrier while securely mounting it to the jack before placing it within the axle housing. Proper bolt thread cleaning is essential before new differential carrier housing bolt installation while maintaining a cross bolt tightening scheme at 203 Nm (150 ft. lbs.). Aligning studs should remain until several bolts are installed. Install the axle shafts along with reattaching the driveshaft connections and then reconnect the rear anti-lock sensor electrical wiring if the vehicle has this component. Add lubricating fluid to the axle space by removing its fill plug until the fluid reaches the fill hole's level before installing the cleaned fill plug. Hamilton last removes wheel chocks before letting go of the parking brake.
