Solution

1. Tire Inspection and Balancing

Sub-steps:
1. Remove the wheel covers (if applicable) and loosen the lug nuts while the vehicle is on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheels and inspect the tires for uneven wear or damage.
4. If necessary, take the wheels to a tire shop for balancing.
5. Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs for Outback).

2. Suspension Component Inspection

Sub-steps:
1. Visually inspect suspension components for any signs of wear, such as cracked bushings or leaking struts.
2. If any components are damaged, replace them with OEM (Original Equipment Manufacturer) parts.
3. Ensure that all fasteners are tightened to the correct torque specifications.

3. Alignment Check

Sub-steps:
1. After any repairs or part replacements, take the vehicle to a professional alignment shop.
2. Have a four-wheel alignment performed to ensure proper handling and tire wear.
3. Verify that the steering wheel is centered after the alignment.
