Solution

1. Preparation

Gather tools including a jack, jack stands, torque wrench, and wheel chocks.
Ensure the vehicle is parked on a flat surface, and set the parking brake.

2. Tire Inspection

Sub-steps:
1. Use a tire pressure gauge to check all tires; inflate to the manufacturer's recommended pressure if needed.
2. Inspect tires for uneven wear patterns, punctures, or bulges; replace any damaged tires.

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Request a four-wheel alignment and adjust camber, caster, and toe angles to specifications as indicated by the manufacturer.

4. Suspension Component Check

Sub-steps:
1. Visually inspect shocks and struts for leaks and physical damage.
2. Check bushings for cracks or excessive wear; replace as necessary.
3. If any components are worn, replace with OEM or high-quality aftermarket parts.

5. Steering System Inspection

Sub-steps:
1. Raise the front of the vehicle using a jack and secure with jack stands.
2. Check for play in tie rods and ball joints by manually moving them; replace any failing components.
3. Tighten any loose bolts to the manufacturer's torque specifications.

6. Frame Inspection

Sub-steps:
1. Conduct a visual inspection of the frame for any signs of bending or damage.
2. If damage is found, consult a professional for repair options.
