Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Change Differential Fluid

Sub-steps:
1. Locate the differential drain and fill plugs.
2. Use a socket wrench to remove the drain plug and drain the old fluid into a suitable container.
3. Inspect the old fluid for metal shavings or debris.
4. Replace the drain plug and torque it to the manufacturer's specifications (typically around 30 ft-lbs).
5. Remove the fill plug and use a fluid pump to fill the differential with new fluid (Toyota recommends SAE 75W-90 gear oil).
6. Replace the fill plug and torque to specifications.

3. Inspect and Replace Differential Bearings (if necessary)

Sub-steps:
1. If noise persists, remove the differential from the vehicle.
2. Disassemble the differential case to access the bearings.
3. Inspect the bearings for wear or damage; replace if necessary.
4. Reassemble the differential with new bearings and shims, ensuring proper preload.
5. Reinstall the differential back into the vehicle.

4. Check Driveshaft and Universal Joints

Sub-steps:
1. Inspect the driveshaft for any signs of damage or excessive play.
2. Check the universal joints for smooth movement; replace if there is any binding or play.
3. Reinstall the driveshaft and torque the bolts to specifications (typically around 15 ft-lbs).
