Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, differential fluid pump, drain pan.
Safety Warnings: Ensure the vehicle is securely lifted and supported before working underneath. Wear safety glasses and gloves.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the drain plug using a socket wrench and allow the fluid to completely drain.
Inspect the old fluid for metal shavings or debris that indicates wear.

3. Inspect and Replace Components

Inspect Gears: Remove the differential cover to access the gears. Check for pitting, scoring, or unusual wear.
Replace Bearings: If wear is found, remove the bearing caps and replace the differential bearings. Use a puller if necessary.
Check Seals: Inspect and replace any worn seals to prevent leaks.

4. Reassemble Differential

Clean the differential housing and the mating surfaces of the cover.
Apply a new gasket or sealant as required.
Reinstall the differential cover and torque the bolts to the manufacturer’s specifications.

5. Refill Differential Fluid

Using a fluid pump, refill the differential with the correct type and amount of fluid specified in the owner’s manual.
Replace the fill plug securely.
