Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, tire pressure gauge, torque wrench, wheel balancer.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Sub-steps:
1. Use the lug wrench to remove the wheel nuts and take off the wheels.
2. Inspect tires for uneven wear; replace if they are worn beyond tread limits.
3. Check tire pressure and inflate to the manufacturer's specifications.
4. If tires are in good condition, proceed to balance them using the wheel balancer.
5. Reinstall wheels and torque the lug nuts to the specified value (usually 80-100 ft-lbs for Honda Accord).

3. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect all suspension components (control arms, tie rods, struts) for signs of wear or damage.
2. If any parts are worn, replace them according to the service manual specifications.
3. Ensure all bolts are tightened to the manufacturer's specifications.

4. Wheel Alignment

Sub-steps:
1. After suspension repairs, take the vehicle to a professional alignment shop.
2. Have the alignment checked and adjusted to the manufacturer's specifications.
