DIFFERENTIAL SIDE OIL SEAL
REPLACEMENT
1) Lift up vehicle and drain transmission oil.
2) Remove drive shaft joints from differential gear of transmis-
sion.
Refer to Section 4 for procedure to disconnect drive shaft
joints.
For differential side oil seal removal, it is not necessary to
remove drive shafts from steering knuckle.
For 4WD vehicle, remove transfer referring to Section 7D.
3) Remove differential side oil seal (1) by using flat end rod or
like.
4) Install new differential side oil seal by using special tool.
Special tool
(A) : 09940-53111
(B) : 09913-75510
5) Install drive shaft referring to Section 4.
6) Refill A/T fluid referring to “FLUID CHANGE” in this section. NOTE:
For oil seal installation, press-fit oil seal so that transmis-
sion case end face is flush with oil seal end face.

OIL CHANGE
1) Before changing or inspecting oil, be sure to stop engine and
lift vehicle horizontally.
2) With vehicle lifted up, check oil level and leakage. If leakage
exists, correct or repair it.
3) Drain old oil, tighten drain plug (3) after applying sealant to
its thread and fill new specified oil as shown below by speci-
fied amount (roughly up to level hole).
“A” : Sealant 99000-31230
Tightening torque
Transfer oil drain plug (a) : 21 N·m (2.1 kg-m, 15.5 lb-ft)
Transfer gear oil
:Hypoid gear oil API GL-5
For oil viscosity, refer to the chart.
Oil Capacity
: 0.5 liters (1.1/0.9 US/lmp. pt)
