Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat, level surface and the engine is off.
Safety warning: Always engage the parking brake before starting work.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires as necessary to match the manufacturer’s recommended pressure, typically found on the driver's door jamb.
Re-check pressure after adjustments to ensure accuracy.

3. Wheel Alignment

Take the vehicle to a certified alignment shop.
Request a four-wheel alignment check.
Adjust camber, caster, and toe angles to align with manufacturer specifications.

4. Suspension Inspection and Repair

Raise the vehicle using a jack and secure it with jack stands.
Inspect all suspension components for wear and tear:
- Check for fluid leaks in shocks and struts.
- Look for play in the ball joints and tie rods.
- Replace any damaged components as necessary.
Reassemble any components removed during inspection.

5. Tire Rotation

Rotate tires according to the vehicle's maintenance schedule or when uneven wear is detected.
Ensure proper tightening of lug nuts to the manufacturer's specified torque.
