Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery cable for safety.

2. Check Differential Fluid

Tools required: Socket set, fluid pump
Remove the differential fill plug using a socket.
Inspect the fluid level; if low, add the appropriate differential fluid until it reaches the fill hole.
Check the fluid condition; if it appears dark or contaminated, proceed to change the fluid.

3. Replace Differential Fluid

Tools required: Fluid drain pan, funnel
Place a fluid drain pan under the differential.
Remove the drain plug and allow old fluid to completely drain.
Clean the drain and fill plugs, then replace the drain plug with a new seal if necessary.
Refill the differential with the manufacturer-recommended fluid type using a funnel until it reaches the fill hole.

4. Inspect and Replace Worn Components

Tools required: Wrench set, torque wrench, bearing puller
Remove the differential housing cover if noise persists after fluid change.
Inspect gears, bearings, and seals for signs of wear or damage.
Replace any worn components, ensuring to torque all bolts to the manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the differential cover with a new gasket or sealant.
Torque the cover bolts to the specified value.
Reconnect the battery and lower the vehicle from the jack stands.
