Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and securely supported.
Disconnect the battery to ensure safety while working.

2. Inspect and Change Differential Fluid

Tools Required: Socket set, drain pan, funnel, torque wrench.
Sub-steps:
1. Place the drain pan under the differential.
2. Remove the differential drain plug and allow fluid to drain completely.
3. Inspect the old fluid for metal shavings or discoloration.
4. Reinstall the drain plug with the specified torque (usually around 30 lb-ft).
5. Remove the fill plug and add new differential fluid as per manufacturer specifications (typically 75W-90 GL-5).
6. Reinstall the fill plug with the specified torque.

3. Inspect Differential Components

Tools Required: Socket set, flashlight, inspection mirror.
Sub-steps:
1. Remove the differential cover if applicable.
2. Inspect gears and bearings for wear or damage (look for pitting or scoring).
3. Check the ring and pinion gears for proper alignment and tooth condition.
4. If damaged, replace necessary components (gears, bearings).

4. Reassemble and Test

Sub-steps:
1. Reinstall the differential cover if it was removed, ensuring an even bead of gasket maker or new gasket is used.
2. Torque the cover bolts to manufacturer specifications.
3. Reconnect the battery.
4. Test drive the vehicle to check for noise and functionality.
