Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Multimeter
Sub-steps:
- Ensure the vehicle is parked on a level surface.
- Turn off the ignition and disconnect the battery to ensure safety.
- Gather necessary tools and replacement parts.

2. Inspect Suspension Components

Sub-steps:
- Use a jack to lift the vehicle and secure it with jack stands.
- Visually inspect the control arms, struts, and bushings for any signs of wear or damage.
- If any components are damaged, remove and replace them, ensuring proper torque specifications are followed.

3. Check Motor Mounts

Sub-steps:
- Locate the motor mounts by referring to the service manual.
- Inspect mounts for any signs of cracks or excessive wear.
- If defective, remove the old mounts and install new ones, ensuring they are torqued to the manufacturer’s specifications.

4. Tire Inspection

Sub-steps:
- Check tire pressures and adjust to manufacturer specifications.
- Inspect the tires for uneven wear patterns and replace if necessary.
- If tire balance is questionable, have the tires balanced professionally.

5. Electrical System Check

Sub-steps:
- Reconnect the battery.
- Use a multimeter to check the battery voltage while the vehicle is off and during idle.
- Ensure voltage remains within the recommended range (typically 12.4V to 12.8V when off and higher while running); replace the battery if failing.
