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

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

Remove the differential carrier. For additional information, refer to Differential Carrier in this article.
Remove and discard the 12 differential ring gear bolts.

CAUTION: Care should be taken not to damage the differential ring gear bolt hole threads.

NOTE: The anti-lock ring cannot be reused once removed.

Insert a punch in the differential ring gear bolt holes. Drive off the differential ring gear and, if necessary, the anti-lock ring.

NOTE: The differential bearings need not be removed to overhaul the Ford limited slip differential.

If necessary, use the special tools to remove the 2 differential bearings.

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.

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.

Inserting the special tool in the pinion shaft bore, turn the differential case to "walk" the 2 differential pinion gears and the 2 differential pinion gear thrust washers out to the differential case windows.

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 or damage to the component may occur.

NOTE: 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.
