2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure all four corners of the vehicle are safely elevated.

3. Inspect and Replace Suspension Components

Inspect Control Arm Bushings:
- Remove any components obstructing access to the control arms.
- Check for cracks or excessive wear in the bushings.
- If damaged, remove the control arm bolts using a socket set and replace the bushings.
Check Sway Bar Links:
- Inspect sway bar links for any breakage or looseness.
- Remove the nuts using a wrench and replace the sway bar links if necessary.
Examine Shock Absorbers:
- Check for any oil leaks or signs of wear on the shock absorbers.
- If defective, remove the shock absorber bolts and replace with new units, ensuring to torque to the manufacturer's specifications.

4. Reassemble and Lower the Vehicle

Reattach all components that were removed during inspection and replacement.
Ensure all nuts and bolts are tightened to the specified torque values.
Carefully lower the vehicle back to the ground.
