Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Differential Fluid Inspection and Replacement

Check Fluid Level
- Remove the fill plug on the differential.
- Insert a dipstick or your finger to check the fluid level; it should be at the bottom of the fill hole.
Drain Old Fluid
- Place a drain pan underneath the differential.
- Remove the drain plug and allow the fluid to completely drain out.
Inspect Fluid Condition
- Check fluid for metal shavings or burnt smell, which indicates internal damage.
Replace with New Fluid
- Reinstall the drain plug and torque it to manufacturer specifications (typically around 25 ft-lbs).
- Fill with new differential fluid, using the recommended type (usually 75W-90) until it reaches the fill hole.
- Reinstall the fill plug and torque to specification.

3. Inspect and Replace Differential Components (if necessary)

Remove Differential Assembly
- If noise persists, lift the vehicle and support it securely on jack stands.
- Remove the wheels and disconnect the driveshaft from the differential.
- Unbolt the differential housing from the vehicle frame and carefully remove it.
Inspect Gears and Bearings
- Check ring and pinion gears for wear or damage.
- Inspect bearings for play or roughness.
Replace Damaged Parts
- If any components are worn, replace them with OEM parts.
- Reassemble the differential with new gaskets and seals as necessary.

4. Reassemble and Test

Reinstall Differential Assembly
- Position the differential back in place and secure it with bolts, torquing to specifications.
- Reconnect the driveshaft.
Reattach Wheels
- Reinstall the wheels and lower the vehicle back to the ground.
Reconnect Battery
- Reconnect the negative battery terminal.
