Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, flashlight
Safely raise the vehicle using a jack and secure it with jack stands.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Inspect Suspension Components

Sub-steps:
- Visually inspect the control arms, bushings, and links for any cracks or wear.
- Use a pry bar to check for excessive play in the ball joints and bushings.
- If any components are damaged, they will need to be replaced.

3. Replace Worn Components

Sub-steps:
- If the shock absorbers are leaking or not functioning properly, remove them:
  1. Remove the bolts securing the shock absorber to the upper mount and lower control arm.
  2. Install the new shock absorber in reverse order of removal, ensuring to torque bolts to manufacturer specifications.
- For worn sway bar links, remove the old link by loosening the nuts on both ends and install the new sway bar link, torquing to manufacturer specifications.

4. Reassemble and Lower Vehicle

Re-check all bolts and ensure everything is tightened to the correct torque specifications.
Carefully lower the vehicle back to the ground.
