Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, flashlight
Safety Warnings: Ensure the vehicle is on a level surface and securely supported with jack stands before working underneath.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the Vehicle: Use a jack to lift the front and rear of the vehicle. Secure it with jack stands.
2. Visual Inspection: Closely examine the struts, control arms, and sway bar links for any visible signs of damage or excessive wear.
3. Check Tightness: Use a torque wrench to ensure that all suspension-related bolts are torqued to the manufacturer’s specifications. Refer to the vehicle's service manual for exact torque values.
4. Pry Bar Test: Use a pry bar to check for play in the ball joints and bushings. If there is excessive movement, these components should be replaced.

3. Replace Worn Components

Sub-steps:
1. Remove Old Components: If any components are found to be defective during inspection, remove them using the appropriate sockets.
2. Install New Parts: Install new ball joints, control arms, struts, or sway bar links as needed, ensuring they are properly aligned and seated.
3. Torque New Fasteners: Secure all fasteners to the specified torque values from the service manual.

4. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall Wheels: If applicable, put the wheels back on, hand-tightening the lug nuts first.
2. Lower the Vehicle: Carefully lower the vehicle back to the ground.
3. Final Torque: Once the vehicle is on the ground, apply final torque to the lug nuts in a criss-cross pattern.
