Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery for safety if working on electronic components.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers (if applicable) using a flathead screwdriver.
2. Inspect each tire for uneven wear patterns; replace tires if they are worn beyond tread depth specifications.
3. Ensure all tires are inflated to the recommended pressure (refer to the owner's manual for specifications).
4. If tire replacement is needed, use a jack and jack stands to lift the vehicle, and remove the wheel using a lug wrench.
5. Install the new tire and torque the lug nuts to the manufacturer’s specifications.

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop for a complete wheel alignment.
2. Ensure that the alignment technician checks the toe, camber, and caster settings against the manufacturer's specifications.
3. If performing alignment yourself, use an alignment tool to adjust the toe settings until they are within specification.

4. Suspension Component Inspection and Replacement

Sub-steps:
1. Inspect control arms, bushings, and struts for wear or damage.
2. If any parts are found defective, replace them with OEM or high-quality aftermarket parts.
3. Torque all bolts to the manufacturer’s specifications after replacement.
