Solution

1. Preparation

Gather tools: socket set, torque wrench, alignment tools, jack stands, and a wheel chock.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working with electrical components.

2. Inspect and Replace Damaged Components

Inspect Suspension and Steering Components
- Examine control arms, tie rods, and strut assemblies for cracks or bends.
- If damaged, replace the affected components using a socket set.
Replace Damaged Tires
- Check for bulges or abnormalities in the tire tread.
- If necessary, remove the damaged tire using a jack and socket set, then install a new tire, ensuring proper torque (typically 80-100 ft-lbs for lug nuts).

3. Wheel Alignment

Perform Wheel Alignment
- Use an alignment tool to adjust the toe, camber, and caster settings according to the manufacturer's specifications.
- Ensure that all adjustments are tightened to the recommended torque values.

4. Check Power Steering System

Inspect Power Steering Fluid
- Check the power steering fluid level and condition.
- If low, top it up with the appropriate fluid (typically ATF or specific power steering fluid as recommended).
Bleed the Power Steering System
- Turn the steering wheel from lock to lock to remove any air trapped in the system.
