1. Remove the differential case. For additional information, refer to Differential Case in this section. 2. NOTE: The differential bearings need not be removed to overhaul the Ford limited slip differential. If bearing removal is required, for additional information, refer to Differential Case in this section. NOTE: The anti-lock speed sensor ring cannot be reused once removed. Remove the differential pinion shaft lock bolt and remove the differential pinion shaft. ? If required, remove the ring gear and anti-lock speed sensor ring. 3. NOTE: This tool does not have the 1/2-inch drive hole. Install the special tool in a suitable vise. 4. Install the differential case on the special tool 5. Install the special tool in the bottom side gear bore. ? Apply a small amount of grease to the centering hole of the special tool. 6. Install the nut in the upper differential side gear. Hold the nut in position while installing the hex screw. Tighten the hex-head screw until contact is made with the Step Plate 7. Insert a suitable dowel bar in the hole of the nut. Tighten the forcing screw to force the differential side gear away from the differential pinion gears. The dowel bar is used to keep the nut from turning when the forcing screw is tightened. 8. WARNING: Keep fingers/hands away from pinion gears when rotating the differential case with the differential rotating tool. NOTE: Differential pinion thrust washers cannot be removed independently of the differential pinion gears and so must be removed simultaneously with the differential pinion gears. Insert the special tool in the pinion shaft bore and turn the differential case to “walk” the differential pinion gears and differential pinion thrust washers out to the differential case windows. 9. Remove the differential pinion gears and differential pinion thrust washers. 10. Remove the differential side gears and differential clutch packs and tag them RIGHT and LEFT with the shim. CAUTION: When separating the clutch plates and clutch discs, note the sequence in which they are disassembled. They must be reassembled in the same sequence. CAUTION: Do not use acids or solvents when cleaning the differential clutch pack. Wipe components with a clean, lint-free cloth only. Separate the differential clutch discs and clutch plates for cleaning and inspection. Refer to the disassembled view of the limited slip differential case in the Description and Operation portion of this section.
