Solution

1. Preparation

Gather necessary tools and replacement parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety gear such as gloves and safety glasses.

2. Adjust Tire Pressure

Sub-steps:
- Use a tire pressure gauge to check each tire's pressure.
- Inflate or deflate tires to match the specifications found in the owner’s manual or on the door jamb sticker.

3. Inspect and Rotate Tires

Sub-steps:
- Remove the hubcaps if applicable, and inspect tires for uneven wear.
- Rotate the tires if uneven wear is detected, moving front tires to the rear and vice versa.
- Ensure that the tires are reinstalled in the proper direction if they are directional.

4. Perform Wheel Alignment

Sub-steps:
- Use a professional alignment machine to measure the alignment angles (camber, caster, and toe).
- Adjust the alignment settings to match the manufacturer’s specifications using the machine’s instructions.
- Tighten all adjustment bolts to the specified torque values.

5. Inspect Suspension Components

Sub-steps:
- Check tie rods, control arms, and bushings for wear or damage.
- Replace any damaged suspension components as necessary with OEM or equivalent parts.
