Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Differential Fluid

Drain the Differential Fluid:
- Locate the differential drain plug.
- Use a socket wrench to remove the plug and drain the fluid into a suitable container.
- Allow fluid to completely drain.
Inspect the Fluid:
- Check the drained fluid for metal shavings or a burnt smell, which indicates internal damage.
Clean the Drain Plug:
- Clean any debris from the drain plug and inspect the magnet for metal particles.
Refill with New Differential Fluid:
- Replace the drain plug and torque it to the manufacturer's specifications (usually around 30 lb-ft).
- Locate the fill plug and remove it.
- Use a funnel to fill the differential with the recommended fluid type (check the owner’s manual for specifications).
- Replace the fill plug and torque it to the specified value.

3. Inspect and Replace Bearings (if necessary)

Remove the Differential:
- Support the vehicle on jack stands and remove the wheels.
- Disconnect the axle shafts from the differential.
- Remove any additional components that obstruct differential removal (such as exhaust or suspension parts).
- Remove the differential mounting bolts and safely extract the differential from the vehicle.
Inspect Bearings and Gears:
- Check for wear on bearings and gears.
- Replace any damaged bearings and gears with OEM parts.
Reassemble the Differential:
- Reinstall the differential by reversing the removal steps.
- Ensure all bolts are torqued to specifications.
