Subaru Outback (BR): Differential Gear Oil replacement

A: INSPECTION

1) Remove the filler plug, and then check the gear oil. Replace the gear oil if it is contaminated, deteriorated or cloudy. <Ref. to DI-23, REPLACEMENT, Differential Gear Oil.>

2) Check that the gear oil level is within -5 mm (- 0.2 in) from the bottom of the filler plug hole. If the level is low, make sure that there is no oil leakage and refill up to the bottom of filler plug hole.

NOTE: On VA1-types at factory settings, the oil level may be within -14 mm (-0.6 in) from the bottom of the filler plug. This is at normal level, requiring no oil refill.
