Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure all necessary safety equipment is in place (gloves, safety glasses).

2. Adjust Tire Pressure

Sub-steps:
- Use a tire pressure gauge to check the pressure of all tires.
- Inflate or deflate tires as needed to match the recommended pressure found in the owner's manual or on the driver’s door jamb label.

3. Perform Wheel Alignment

Sub-steps:
- Position the vehicle on an alignment rack.
- Follow the manufacturer’s specifications to adjust camber, caster, and toe settings.
- Adjust tie rods as necessary using a torque wrench to ensure all specifications are met (typically around 30-50 ft-lbs depending on the model).

4. Inspect and Replace Worn Components

Sub-steps:
- If any worn suspension parts are found during the visual inspection, replace them.
- For instance, if control arm bushings are cracked, remove the old ones using a socket set and install new bushings.
- Ensure all fasteners are torqued to the manufacturer's specifications.
