How to Change Rear Differential Oil of Subaru Forester

Step 1: Lift up vehicle a little bit. Since you'll need some free space to handle 24'' wrench to loosen the differential 1/2" plugs.

Step 2: Loosen the upper plug first. If you can not be succeed still you will have a chance to call mechanic. Otherwise the lower plug will drain the oil.
The oil will start to bleed a little. Put your waste oil container below the plug.

Step 3: Now loosen the lower plug and drain the full oil.

Step 4: Differential needs 0.8 liters of 75-90 GL-5 performance level oil. You may need a plastic pipe to reach differential. I choose a plastic container and put a pipe on it. Fill up the differential till it starts bleeding from the upper plug hole.

Tightening torque for the plugs: 49 NM
