9.75" & 10.25" Differential
NOTE:
Pinion gears are installed with preload. Thrust washers cannot be removed alone. Preload must be released and gears must be rotated out of case with thrust washers.
- Remove ring gear. DO NOT remove ABS sensor ring (if equipped). If sensor ring is removed, it must be replaced. Remove pinion shaft lock bolt and pinion shaft. Install Traction-Lok Torque Tool (T97T-4205-A) upright in a vise. Position differential case on tool. Install a lubricated Step Plate Adapter (D80L-630-5) or equivalent into bottom gear spline.
- Install Mandrel (T97T-4946-A) in upper facing side gear with nut positioned against mandrel. Tighten hex-head forcing screw until contact is made with step plate adapter. Use a bar to hold the nut and tighten forcing screw until preload pressure is released. See Fig 1 .
- Insert pinion gear rotating tool into pinion shaft bore and turn differential case to rotate gears and thrust washers into carrier windows. Remove pinion gears ans thrust washers. Remove differential side gears and clutch packs. Mark gears and clutch packs LEFT and RIGHT for reassembly reference.
