Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repairs.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the hubcaps or wheel covers if applicable.
2. Loosen the lug nuts slightly while the car is on the ground.
3. Jack up the vehicle and securely place it on jack stands.
4. Remove the lug nuts and take off the wheels.
5. Inspect each tire for tread wear; if any tire has less than 2/32 inch of tread, replace it.
6. Ensure all four tires are of the same type and brand; replace mismatched tires if necessary.
7. Reinstall the wheels, hand-tighten the lug nuts, lower the vehicle, and torque the lug nuts to the manufacturer’s specifications.

3. Brake Inspection and Maintenance

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect the brake pads for wear; replace if they are less than 3mm thick.
3. Check the brake rotors for any scoring or warping; replace if necessary.
4. Clean any dust or debris from the brake calipers and pads.
5. Reassemble the brake components and wheel, ensuring proper torque on the lug nuts.

4. Suspension Inspection and Repair

Sub-steps:
1. Check for any leaks in the shock absorbers; replace if leaking or damaged.
2. Inspect control arms, bushings, and all other suspension parts for wear.
3. If any components are worn, remove them and install new parts according to manufacturer specifications.
4. Align the wheels if suspension components were replaced.
