Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect Suspension Components

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the struts, shock absorbers, sway bar links, and control arms for any signs of damage or wear.
3. Check the bushings for cracks or deterioration.

3. Tighten Loose Components

Sub-steps:
1. Using a socket set, check the torque on all suspension bolts and fasteners.
2. Tighten any loose bolts to the manufacturer’s specifications, usually found in the service manual.

4. Replace Worn Components

Sub-steps:
1. If any components (sway bar links, bushings, struts) are found to be worn or damaged, remove them using the socket set.
2. Install new components, ensuring they are properly aligned.
3. Tighten all fasteners to the manufacturer’s torque specifications.

5. Final Inspection

Sub-steps:
1. Once repairs are made, lower the vehicle back to the ground.
2. Reconnect the negative battery terminal.
3. Perform a final inspection of all components and ensure nothing is obstructed.
