Solution

1. Preparation

Gather tools and materials: wheel chocks, jack stands, socket set, torque wrench, alignment tool, tire pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection and Pressure Adjustment

Sub-steps:
- Check the tire pressure using a tire pressure gauge; inflate or deflate to match the specifications found on the driver’s side door jamb.
- Visually inspect tires for any signs of bulging, punctures, or uneven wear.
- Replace any tires that show significant wear or damage.

3. Alignment Check and Adjustment

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Use a laser alignment tool to check the front and rear wheel alignment.
- If misalignment is detected, adjust the alignment bolts according to the manufacturer's specifications (usually requires a torque wrench for proper settings).

4. Suspension Component Inspection

Sub-steps:
- Visually inspect the suspension components for any signs of wear or damage.
- Check for loose or damaged bushings, ball joints, and struts; replace any worn parts.
- Tighten any loose bolts to the manufacturer's torque specifications.
