2003 Ford F-350 Super Duty Differential Parts Questions & Experts Answers
- Q: How to service and repair the Dana S135 rear axle differential carrier on 2003 Ford F-350 Super Duty?A: Before servicing or repairing the Dana S135 rear axle differential carrier operators should begin by cleaning the axle with steam to stop abrasive dirt from speeding up its degradation. A suitable container should receive the axle lubricant while the parking brake remains engaged after you remove the drain plug to drain the fluid before reinstalling the plug. For servicing or repair of the Dana S135 rear axle differential carrier begin by disconnecting the rear anti-lock brake sensor electrical connector, marking and removing the driveshaft and then remove the pinion hex nut if you need to disassemble this component. Direct steel hammer blows to the axle shaft flange may lead to cracks so strike it away from the hub area and mark the flange for reinstallment orientation. Separate the axle shafts while keeping only two top carrier-to-axle housing retaining bolts in place. Document the lengths and positions of the bolts. Secure the carrier to a jack but allow it to fall away so you can remove remaining bolts until the carrier separates from the axle housing by 25.4 - 50.8 mm (1 - 2 inches). The components require rinsing with emulsion cleaners or petroleum-based solvents before towel drying with lint-free cloths and coating with rust preventive solutions or clean lubricants for storage protection by component wrapping. Check for damage as well as pitting on the gear set while inspecting splines for wear and the axle flange O-ring. Inspection of stripped threads and bending fatigue should be performed on the axle housing interior sealing surface after cleaning both areas. You should check the differential case and ring gear if disassembly of the components becomes essential. Use Ford Gasket Maker F8AZ-19B508-AB as a continuous bead around each bolt hole and the mounting flange of the axle housing before inserting two studs at opposite angles to stop the carrier assembly from rotating. Begin by attaching the carrier to the jack then placing it inside the axle housing. Before inserting bolts, treat the bolt threads with Threadlock 262 E2FZ-19554-B followed by bolt installation until you remove the alignment studs between several bolt installations. First follow a cross pattern when tightening bolts before adding axle shafts above the driveshaft and reestablishing connections for both components. Screw off the fill plug to put Motorcraft SAE 80W-90 Premium Rear Axle Lubricant XY-80W90-QL into the axle while keeping the lubricant at the fill hole level. Afterwards install and wipe clean the fill plug. The parking brake should be released as the wheel chocks need to be fully removed.
