Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the rear of the vehicle using a jack and secure with jack stands.

2. Fluid Inspection and Replacement

Drain Differential Fluid
- Locate the differential drain plug and use a socket wrench to remove it.
- Allow the fluid to completely drain into a suitable container.
Inspect Fluid Condition
- Check the drained fluid for metal shavings or a burnt smell, which can indicate internal damage.
Replace Fluid
- Reinstall the drain plug and tighten to manufacturer specifications (usually around 30-40 ft-lbs).
- Remove the fill plug and use a fluid pump to add new differential fluid until it reaches the fill hole. Use the fluid type specified by the manufacturer (typically 75W-90 gear oil).

3. Bearing and Gear Inspection

Remove Differential Cover
- If the fluid condition indicates potential internal damage, remove the differential cover by unbolting it with a socket set.
- Clean the mating surfaces of the differential housing and cover.
Inspect Gears and Bearings
- Inspect the gears for wear patterns and chips.
- Check the bearings for excessive play or roughness by rotating them by hand.
Replace Damaged Components
- If any gears or bearings are worn or damaged, replace them with OEM parts following manufacturer specifications.

4. Reassemble and Test

Reinstall Differential Cover
- Apply a new gasket or sealant to the differential cover if needed.
- Bolt the cover back onto the differential and tighten to manufacturer specifications.
Test Drive
- Lower the vehicle, remove jack stands, and take the vehicle for a test drive to confirm the noise has been resolved.
