Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, OBD-II scanner, fluid pump.
Ensure the vehicle is parked on a level surface and disable the ignition.
Lift the vehicle using a jack and secure it with jack stands.

2. Inspect Drivetrain Components

Sub-steps:
- Remove the undercarriage shield if applicable.
- Visually inspect the CV joints and axles for cracks or damage.
- Check the condition of the driveshaft for any play or unusual wear.

3. Transmission Fluid Inspection

Sub-steps:
- Locate the transmission dipstick or fill plug.
- Remove the dipstick or fill plug and check the fluid level and condition (should be a bright red color).
- If low, add the manufacturer's recommended transmission fluid until the proper level is reached.

4. Engine Mount Inspection

Sub-steps:
- Inspect engine mounts for signs of cracking or separation.
- Replace any damaged mounts using a socket set to unbolt and remove the mount, then install a new mount using the manufacturer’s torque specifications.

5. Differential Fluid Inspection

Sub-steps:
- Locate the differential fill plug and remove it.
- Check the fluid level and condition; it should be clean and without metal shavings.
- If low, use a fluid pump to fill with the manufacturer-recommended differential fluid until it begins to seep out of the fill hole.
