bent tip screwdriver, remove the quick connect
fitting retaining ring (3) from the quick connect
fitting (4) and discard the retaining ring.
4.2. Remove the differential cooler inlet pipe from
the differential nut.
Drain the fluid.
Filling Procedure:
If not equipped with a differential cooler, install the
drain plug (1) and washer (2) to the differential.
Tighten the differential drain plug to 35 N•m (26 lb
ft).
If equipped with a differential cooler: 2.1. Install a
new retaining ring.
2.2. Connect the differential cooler pump inlet pipe
(2) to the differential. A distinct snap should be
heard or felt when assembling the cooler pipe to
the fitting.
2.3. To ensure the cooler line is properly installed,
give the cooler pipe a gentle pull.
Clean any dirt from around the differential fill plug.
Remove the fill plug and washer from the
differential.
Important: DO NOT add any limited-slip additive
(friction modifier). With this new fluid (Dexron LS
Gear Oil 75W-90) it is no longer required to add
friction modifier. If friction modifier is added, it will
cause the fluid to lose some of it's friction reducing
properties as well as reducing seal life.
Fill the differential with the new DEXRON® LS gear
oil, P/N 88862624 (Canadian P/N 88862625). Refer
to the table listed below for lubrication
specifications.
Check the fluid level to ensure it is even with the
bottom of the fill plug hole to no lower than 6 mm
(0.25 in) below the opening. Install the fill plug and
washer to the differential. Tighten the differential
fill plug to 35 N•m (26 lb ft).
Important: Steps 8-13 are for vehicles equipped
with the differential cooling system. For vehicles not
equipped with the cooling system, proceed to step
14.
