Disconnect the 12V battery for safety.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for thickness and wear; replace if less than 3mm.
3. Check the brake rotors for scoring or damage; replace if necessary.
4. Reassemble the brake components and wheel, and torque bolts to manufacturer specifications.

3. Check and Replace Drivetrain Components

Sub-steps:
1. Inspect the driveshaft and axles for any visible damage or looseness.
2. Tighten any loose bolts or components to the specified torque values.
3. If damaged, replace with OEM parts, ensuring proper alignment during installation.

4. Inspect Wheel Bearings

Sub-steps:
1. Jack up the vehicle and remove the wheel.
2. Spin the hub and listen for any grinding or roughness.
