Solution

1. Tire Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect all tires for signs of wear, bulges, or foreign objects embedded.
3. Rotate or replace tires if uneven wear is detected.
Tools Required: Jack, jack stands, tire pressure gauge.

2. Brake Inspection

Sub-steps:
1. Remove the wheel to access the brake caliper and rotor.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Check the rotor for scoring or excessive wear; replace if necessary.
4. Reassemble wheel after inspection.
Tools Required: Socket set, brake pad gauge, torque wrench.

3. Suspension Check

Sub-steps:
1. Visually inspect all suspension components (shocks, struts, control arms) for signs of wear or damage.
2. Check for loose bolts or bushings; tighten or replace as needed.
3. If noise persists, consider a more detailed inspection of the strut mounts and bearings.
Tools Required: Socket set, pry bar.

4. Diagnostic Scan

Sub-steps:
1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Review any stored error codes related to the drivetrain or suspension.
3. Address any issues indicated by the codes, which may involve specific repairs based on diagnostics.
Tools Required: OBD-II scanner.
