Solution

1. Preparation

Gather all necessary tools and materials.
Tools Required:
- Socket set
- Torque wrench
- Clean rags
- Differential fluid (specific to Subaru specifications)

2. Access the Differential

Sub-steps:
- Lift the rear of the vehicle using a jack and secure it with jack stands.
- Locate the differential fill plug, usually on the top or side of the differential housing.

3. Check Fluid Level

Sub-steps:
- Remove the fill plug using the socket set.
- Insert a clean finger into the fill hole; the fluid should be just below the edge of the hole. If fluid drips out, the level is adequate.
- If the fluid level is low, proceed to add fluid.

4. Add Differential Fluid

Sub-steps:
- Using a fluid pump, fill the differential with the appropriate fluid until it begins to seep out of the fill hole.
- Replace and tighten the fill plug to the manufacturer’s torque specifications (typically around 30 ft-lbs).
- Wipe any spilled fluid from the housing.
