Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace Drive Components

Remove the Undercover (if applicable)
- Use a socket set to remove bolts securing the undercover.
- Carefully lower and set aside.
Check Drive Belts and Pulleys
- Visually inspect belts for cracks or fraying; replace if damaged.
- Use a wrench to adjust tension if necessary; ensure it's within manufacturer specifications.
Inspect Differential and Transmission Fluid
- Locate the transmission and differential access points.
- Use a fluid extractor to check fluid condition and levels.
- Refill with manufacturer-recommended fluid if low or replace if contaminated.
Examine Wheel Bearings and CV Joints
- Lift the vehicle using a jack and secure with jack stands.
- Spin wheels by hand to check for roughness in bearings; replace if necessary.
- Inspect CV joints for any signs of damage or wear.

3. Reassemble Vehicle

Reinstall the undercover and secure with previously removed bolts.
Reconnect the battery and ensure all connections are tight.
