Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather tools and parts needed for the repair.
Tools Required: Jack, jack stands, socket set, torque wrench, fluid pump, differential fluid, OBD-II scanner.

2. Fluid Inspection and Replacement

Inspect the Differential Fluid:
- Remove the fill plug on the differential.
- Check fluid level; it should be at the bottom of the fill hole.
- If the fluid is dark, burnt, or contains metal shavings, replacement is necessary.
Replace the Differential Fluid (if needed):
- Drain the old fluid by removing the drain plug.
- Allow the fluid to completely drain into a container.
- Clean the drain plug and inspect the magnet for metal shavings.
- Reinstall the drain plug and torque to manufacturer's specifications (typically around 30 ft-lbs).
- Use a fluid pump to fill the differential with new fluid until it begins to seep from the fill hole.
- Reinstall the fill plug and torque it to specifications (approximately 30 ft-lbs).

3. Inspect and Replace Components

Check Drive Shafts and CV Joints:
- Lift the vehicle and remove the wheels for better access.
- Inspect the drive shafts for any signs of wear, such as cracks or torn boots.
- If damaged, replace the affected drive shaft or CV joint.
Examine Differential Mounts:
- Inspect the differential mounting points for any signs of looseness or wear.
- Tighten or replace any worn mounts as necessary.
