Solution

1. Tire Pressure Adjustment

Sub-steps:
- Use a tire pressure gauge to measure tire pressure.
- Inflate or deflate tires to match the recommended pressure found in the owner's manual or on the driver’s side door jamb.

2. Wheel Alignment

Sub-steps:
- Drive the vehicle onto an alignment rack.
- Use alignment equipment to measure camber, caster, and toe angles.
- Adjust the alignment settings as necessary to bring them within the manufacturer’s specifications.

3. Suspension Component Inspection and Repair

Sub-steps:
- Lift the front of the vehicle using a jack and secure it with jack stands.
- Inspect struts, shocks, control arms, and bushings for signs of wear or damage.
- Replace any worn or damaged components with OEM or quality aftermarket parts.

4. Tire Rotation (if necessary)

Sub-steps:
- Remove all four tires using a socket set.
- Rotate the tires in a crisscross pattern (front left to rear right and vice versa).
- Reinstall tires and torque lug nuts to the manufacturer’s specifications.

5. Balancing Tires (if necessary)

Sub-steps:
- Remove the tires from the vehicle.
- Mount each tire on a tire balancer.
- Add weights as needed to achieve balance, following the balancer's specifications.
