Differential Case and Ring Gear - Traction-Lok®: Disassembly

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

Remove the differential case. For additional information, refer to DIFFERENTIAL CASE .

NOTE: The differential bearings need not be removed to overhaul the Ford limited slip differential. If bearing removal is required, use the 2-Jaw Puller.

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.
- Discard the differential pinion shaft lock bolt.
- If required, remove the ring gear and anti-lock speed sensor ring.

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.

WARNING: Keep fingers and 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 must be removed simultaneously with the differential pinion gears

Fig 7: Inserting Special Tool In Pinion Shaft Bore

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.
Remove the differential pinion gears and differential pinion thrust washers.

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.
