Rear Differential Symptom Diagnosis

Condition
Gear noise
Bearing noise
Oil leakage

Rear Differential Oil Change

NOTE
It is highly recommended to use SAE 80W-90
viscosity.
1) Before oil change or inspection, be sure to stop
engine and set vehicle horizontally.
2) Check oil level and existence of leakage. If leakage
is found, correct its cause.
3) Remove level/filler and drain plugs, then drain old oil.
4) Apply sealant to thread of drain plug (2), if reused.
5) Tighten drain plug (2) to specified torque.
"A": Sealant 99000–31260
Tightening torque
Oil drain plug (b): 21 N·m (2.1 kgf-m, 15.5 lb-ft)
6) Pour proper amount of new gear oil as specified in
the following (roughly up to level hole).
7) Apply sealant to thread of level/filler plug (1) if
reused.
8) Tighten level/filler plug (1) to specified torque, after
applying sealant to its thread.
"A": Sealant 99000–31260
Tightening torque
Oil level/filler plug (a): 21 N·m (2.1 kgf-m, 15.5
lb-ft)
