Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear safety goggles and gloves.

2. Inspect and Adjust Tire Pressure

Sub-steps:
- Use a tire pressure gauge to check the pressure in each tire.
- Inflate or deflate tires to reach the recommended pressure as specified in the owner’s manual.

3. Wheel Alignment

Sub-steps:
- Lift the vehicle using a hydraulic jack and secure it on jack stands.
- Remove the front wheels for easier access to the suspension.
- Use a wheel alignment machine to check alignment settings (camber, caster, toe).
- Adjust alignment settings to manufacturer specifications as needed.

4. Inspect Suspension Components

Sub-steps:
- Visually inspect control arms, tie rods, and bushings for wear or damage.
- Replace any worn or damaged components with OEM parts.
- Reassemble any components that were removed for access.

5. Rotate Tires

Sub-steps:
- Remove the wheels and rotate them according to the manufacturer’s recommended pattern (usually front to back).
- Reinstall wheels and torque lug nuts to specification (typically 80-100 ft-lbs).

6. Final Check

Sub-steps:
- Lower the vehicle back to the ground and perform a final check of tire pressures.
- Test drive the vehicle to ensure stability and alignment are corrected.
