Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery for safety.

2. Fluid Change

Drain the existing differential fluid:
- Locate the drain plug on the differential.
- Use a socket set to remove the drain plug and allow fluid to fully drain into a pan.
Replace the differential fluid:
- Reinstall the drain plug and tighten to manufacturer specifications (usually around 30 ft-lbs).
- Remove the fill plug and use a funnel to add new differential fluid (check the owner's manual for the correct type and capacity).
- Reinstall the fill plug securely.

3. Inspection of Components

Inspect the differential housing:
- Look for cracks or damage on the differential case.
Examine the driveshaft and axles:
- Check for any signs of wear, such as torn CV boots or excessive play in the joints.
Test the differential:
- If the vehicle has a limited-slip differential, perform a test to see if it engages properly during turns.

4. Replace Components (if needed)

If any parts are found defective (e.g., worn bearings or damaged gears):
- Disassemble the differential carefully according to service manual instructions.
- Replace the damaged components with OEM parts.
- Reassemble the differential ensuring all components are properly aligned and torqued to specifications.
