Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a level surface and secure it with jack stands.
Disconnect the battery to prevent any electrical issues.

2. Drain Differential Fluid

Place a drain pan under the rear differential.
Remove the drain plug using the appropriate socket.
Allow the fluid to fully drain into the pan.
Inspect the fluid for metal shavings or debris, indicating wear.

3. Inspect Components

Remove the rear differential cover by unscrewing all bolts.
Inspect the gears, bearings, and internal components for wear or damage.
Check for any signs of pitting on gears or discoloration on bearings.

4. Replace Worn Components

If any gears or bearings are worn, remove them carefully.
Replace with OEM or high-quality aftermarket parts, ensuring correct specifications.
Apply a thin layer of gear oil to new bearings before installation.

5. Reassemble Differential

Clean the mating surfaces of the differential cover and housing.
Apply a new gasket or RTV sealant to the cover.
Reinstall the cover and torque the bolts to the manufacturer's specifications (usually around 30-40 lb-ft).
Replace the drain plug and torque to specified values.

6. Fill with New Differential Fluid

Use a fluid pump to add the correct type of differential fluid (usually 75W-140 or as specified by the owner’s manual).
Fill until the fluid reaches the fill hole.

7. Test Drive

Reconnect the battery.
Test drive the vehicle to ensure the noise is no longer present.
