Solution

1. Preparation

Tools Required: Jack stands, tire iron, torque wrench, OBD-II scanner, flashlight, and a multimeter.
Make sure the vehicle is parked on a flat surface, and the ignition is off.

2. Inspect Suspension Components

Sub-steps:
1. Lift the front of the vehicle using a jack and secure with jack stands.
2. Remove the front wheels using a tire iron.
3. Visually inspect suspension components such as control arms, bushings, and struts for wear or damage.
4. Replace any damaged components with OEM parts, ensuring to torque bolts to manufacturer specifications.

3. Check Wheel Bearings

Sub-steps:
1. After removing the wheel, grasp the wheel hub and attempt to shake it side-to-side.
2. Listen for any grinding noises while spinning the hub.
3. If bearings are found to be defective, replace them using a bearing puller and install new bearings, ensuring proper lubrication.

4. Examine Tires

Sub-steps:
1. Inspect the tires for uneven wear or damage.
2. Check tire pressure and inflate to the recommended PSI.
3. Rotate or replace tires as necessary to ensure even wear.

5. Test Drivetrain Components

Sub-steps:
1. Examine the driveshaft and CV joints for any visible damage.
2. Ensure all bolts and fasteners are tight and secure.
3. If any drivetrain issues are found, consult the manufacturer for replacement parts.
