Solution

1. Preparation

Tools Required:
- Floor jack and jack stands
- Wrench set
- Socket set
- Drain pan
- Torque wrench
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported before working underneath.

2. Differential Fluid Change

Drain Fluid
- Place a drain pan under the differential.
- Remove the drain plug using the appropriate socket.
- Allow the old fluid to completely drain out.
Inspect Fluid Condition
- Check the drained fluid for metal shavings or a burnt smell, indicating internal wear.
Replace Fluid
- Reinstall the drain plug and torque to the manufacturer’s specification.
- Remove the fill plug and use a fluid pump to fill the differential with new fluid until it starts to seep from the fill hole.
- Reinstall the fill plug and torque to the manufacturer’s specification.

3. Inspect and Replace Worn Components

Visual Inspection
- Inspect the differential housing, CV joints, and axles for any visible signs of wear or damage.
Replace Components if Necessary
- If any components are worn, remove and replace them as needed:
  - CV Joints/Axles: Use a socket set to remove the axle nuts and disconnect the axles from the differential.
  - Differential Gears/Bearings: This step may require professional assistance if internal components are worn.

4. Transmission Fluid Change (if applicable)

Drain Transmission Fluid
- Place a drain pan under the transmission.
- Remove the transmission drain plug and allow the fluid to drain completely.
Replace Fluid
- Reinstall the drain plug and torque to specification.
- Use a fluid pump to fill the transmission with the appropriate type of fluid until it reaches the correct level.
