Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and allow it to cool if needed.

2. Fluid Inspection

Tools Required: Socket set, differential fluid
Sub-steps:
1. Remove the differential fill plug using a socket.
2. Check the fluid level; it should be at or slightly below the fill hole.
3. Assess fluid condition; it should be clean and free of metal shavings.
4. If the fluid is low or contaminated, drain and replace it.

3. Noise and Vibration Assessment

Tools Required: None
Sub-steps:
1. Drive the vehicle at different speeds and listen for whining or grinding noises.
2. Note any vibrations felt during acceleration or deceleration.
3. If noises or vibrations are present, further inspection of the differential gears may be necessary.

4. Differential Disassembly (if needed)

Tools Required: Socket set, pry bar, torque wrench
Sub-steps:
1. Safely lift the vehicle using a jack and secure with jack stands.
2. Remove the differential cover by unscrewing the bolts.
3. Inspect the gears and bearings for signs of wear or damage.
4. Replace any worn components as necessary (bearings, seals, gears).

5. Reassemble and Refill

Tools Required: Torque wrench, new differential fluid
Sub-steps:
1. Clean the differential cover and apply a new gasket or sealant if needed.
2. Reinstall the cover and tighten bolts to manufacturer specifications.
3. Refill the differential with the appropriate type and amount of fluid.
