Solution

1. Preparation

Tools Required: Tire pressure gauge, jack and jack stands, torque wrench, socket set, stethoscope (if available).
Ensure the vehicle is parked on a level surface and the battery is turned off.
Wear safety glasses and gloves.

2. Tire Inspection

Sub-steps:
1. Visually inspect the tires for uneven wear patterns.
2. Measure tire pressure; inflate to manufacturer specifications if low.
3. Rotate tires if necessary to ensure even wear.

3. Suspension Component Check

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Inspect control arms, bushings, and struts for any signs of damage or wear.
3. Tighten any loose bolts to manufacturer torque specifications.

4. Drive Unit Examination

Sub-steps:
1. Remove the undercarriage cover (if applicable) to access the drive unit.
2. Inspect the drive unit for any signs of oil leaks or physical damage.
3. Listen for unusual sounds while the vehicle is powered on (in neutral).

5. Wheel Bearing Test

Sub-steps:
1. Spin each wheel by hand to detect any roughness or noise.
2. Check for play by grabbing the wheel at 12 o'clock and 6 o'clock and attempting to rock it.
3. Replace wheel bearings if any irregularities are found.

6. Brake System Evaluation

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear and ensure they're within specifications.
3. Check rotors for warping or irregularities; replace if necessary.
