Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to avoid electrical shorts during repairs.

2. Fluid Inspection and Replacement

a. Drain Differential Fluid
- Place a drain pan under the differential.
- Remove the differential drain plug using a socket set.
- Allow fluid to completely drain.
b. Inspect Fluid Condition
- Check for metal shavings or burnt smell indicating internal wear.
c. Refill with New Fluid
- Replace the drain plug with a new washer if necessary.
- Use the manufacturer-recommended differential fluid and fill through the fill plug until it starts to overflow.

3. Inspect and Replace Differential Components

a. Remove Differential Cover
- Remove bolts securing the differential cover using a socket set.
- Gently pry off the cover and clean the mating surfaces.
b. Inspect Gears and Bearings
- Visually inspect the ring and pinion gears for wear or damage.
- Check bearings for signs of pitting or roughness by rotating them by hand.
c. Replace Worn Components
- Replace any damaged gears or bearings.
- Reassemble the differential with new gaskets or sealant as needed.

4. Reassemble and Test

a. Reattach Differential Cover
- Secure the differential cover with bolts, torquing to manufacturer specifications.
b. Refill Differential Fluid
- Ensure the differential is filled to the correct level as previously described.
c. Reconnect Battery
- Reattach the battery terminals ensuring a secure connection.
