Solution

1. Preparation

Gather tools and materials such as a jack, jack stands, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection

Sub-steps:
1. Remove the hubcaps if installed.
2. Use a tire pressure gauge to check the tire pressure; adjust to the manufacturer's specifications.
3. Visually inspect each tire for uneven wear patterns and damage (bulges, cuts).

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect shock absorbers and struts for leaks, dents, or signs of wear.
3. Check control arms, bushings, and sway bar links for any play or damage.

4. Shock Absorber Replacement (if necessary)

Sub-steps:
1. Remove the wheel for easier access to the suspension components.
2. Disconnect the upper and lower mounting bolts of the shock absorber.
3. Remove the old shock absorber and install the new one, ensuring to torque bolts to manufacturer specifications (typically around 25-30 ft-lbs).

5. Alignment

Sub-steps:
1. After replacing any worn components, take the vehicle to an alignment shop.
2. Have a professional perform a four-wheel alignment according to manufacturer specifications.

6. Testing

Sub-steps:
1. Lower the vehicle back to the ground and reattach the wheels.
2. Conduct a test drive to ensure the ride quality has improved.
