Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Tire Inspection

Sub-steps:
1. Remove the hubcaps (if applicable) and inspect the tires for any visible damage or uneven wear patterns.
2. Check tire pressure and inflate to the recommended PSI if necessary.
3. Rotate tires if uneven wear is detected.
Tools Required: Tire pressure gauge, jack, lug wrench.

3. Check Underbody Components

Sub-steps:
1. Use a jack to lift the vehicle safely and secure with jack stands.
2. Inspect the underbody for loose panels, damaged exhaust components, or missing fasteners.
3. Tighten or replace any loose or damaged components as necessary.
Tools Required: Socket set, torque wrench.

4. Suspension Inspection

Sub-steps:
1. Visually inspect the suspension components (shocks, struts, control arms) for signs of wear or damage.
2. Check for any leaking fluids from shock absorbers or struts.
3. Replace any worn or damaged components.
Tools Required: Wrench set, jack stands.

5. Drivetrain Check

Sub-steps:
1. Connect a diagnostic tool to the vehicle’s OBD-II port and check for any fault codes.
