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 for safety.

2. Fluid Change

Tools Required: Socket set, drain pan, funnel, new differential fluid.
Remove the drain plug from the rear differential and allow the old fluid to drain completely into the drain pan.
Inspect the old fluid for metal shavings or debris, which indicates wear.
Replace the drain plug and tighten it to the manufacturer's specified torque.
Use a funnel to fill the differential with new fluid until it reaches the fill hole level.
Replace the fill plug and tighten it to the specified torque.

3. Inspect and Replace Components

Tools Required: Socket set, pry bar, torque wrench.
Remove the rear differential cover if necessary to inspect the gears and bearings.
Check for wear or damage on the ring and pinion gears.
Inspect the differential bearings for play; replace if excessive wear is found.
If any components are damaged, replace them with OEM parts.
Reassemble the differential cover and torque bolts according to specifications.

4. Final Assembly

Reattach any components removed during the inspection (e.g., driveshaft, differential mounts).
Reconnect the negative battery terminal.
Dispose of the old differential fluid according to local regulations.
