Differential Case and Ring Gear - Traction-Lok: Disassembly

WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

Remove the differential carrier. Tag the differential shims and bearing cups for location. For additional information, refer to DIFFERENTIAL CARRIER .
Remove and discard the 12 differential ring gear bolts.

Insert a punch in the differential ring gear bolt holes. Drive off the differential ring gear.
If checking differential case flange runout, install the bearing cups in their original location and install the differential assembly.
1. Install the bearing caps and differential shims.
  - Rotate the differential assembly to verify the bearings have seated.
2. Install the Dial Indicator Gauge With Holding Fixture and record the differential case runout.

Insert a suitable dowel bar in the hole of the nut. Tighten the forcing screw to force the differential side gears away from the differential pinion gears.

NOTE: Differential pinion gear thrust washers cannot be removed independently of the differential pinion gears.

Fig 10: Turning Differential Case

NOTE: When separating the clutch plates and clutch discs, note the sequence in which they are disassembled. They must be reassembled in the same sequence.

NOTE: Do not use acids or solvents when cleaning the differential clutch pack. Wipe components with a clean, lint-free cloth only.
