Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, tire pressure gauge.
Ensure the vehicle is parked on a flat surface and turn off the engine.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the pressure in all tires.
2. Inflate or deflate tires to match the recommended PSI found in the driver’s door jamb.
3. Inspect each tire for signs of damage or uneven wear. Mark any worn areas.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels using a lug wrench.
2. Take the wheels to a tire shop for professional balancing.
3. Reinstall the wheels using the recommended torque value (typically 80-100 ft-lbs for Honda).

4. Wheel Bearing Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Spin each wheel by hand and listen for any unusual noise.
3. Check for wheel play by grasping the wheel at the 12 and 6 o'clock positions and checking for movement.

5. Suspension Component Inspection

Sub-steps:
1. Visually inspect struts, shocks, and suspension bushings for signs of wear or damage.
2. Replace any damaged components as necessary.
3. Tighten any loose bolts to manufacturer specifications.

6. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure the alignment is adjusted to factory specifications.
