Solution

1. Preparation

Tools Required: Socket set, torque wrench, floor jack, jack stands, mechanic's stethoscope, pry bar.
Ensure the vehicle is on a flat surface and securely supported by jack stands.

2. Inspect Suspension Components

Sub-steps:
1. Lift the vehicle using a floor jack and secure it on jack stands.
2. Inspect the upper and lower control arms for cracks or excessive wear.
3. Check the bushings for deterioration or separation from the control arms.
4. Examine the strut mounts and bearings for damage or looseness.

3. Replace Worn or Damaged Parts

Sub-steps:
1. If any parts are found to be damaged or worn, remove the affected components.
2. For control arms, remove the bolts using a socket set and install new control arms, ensuring to torque bolts to manufacturer specifications (typically around 50-70 ft-lbs).
3. Replace strut assemblies if they are leaking or damaged, ensuring to torque all bolts as specified.
4. Reinstall new bushings if necessary, ensuring all are properly lubed and aligned.

4. Reassemble and Lower Vehicle

Sub-steps:
1. Double-check all connections and ensure all components are tightened to specifications.
2. Lower the vehicle from jack stands and remove the jack.
3. Recheck alignment and ensure proper tire pressure is maintained.
