Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Use jack stands to lift the vehicle safely and remove the wheels for access to the suspension components.

2. Inspect and Replace Damaged Components

Inspect Suspension Components:
- Examine struts and shocks for leaks or physical damage.
- If damaged, proceed with replacement.
Replace Struts/Shocks:
- Remove the top mounts and lower bolts securing the strut to the steering knuckle.
- Carefully remove the strut assembly from the vehicle.
- Transfer any necessary components (e.g., spring seats) to the new struts.
- Install the new struts in reverse order, tightening to manufacturer specifications (typically around 25-35 ft-lbs for top mounts).

3. Replace Sway Bar Links (if necessary)

Remove Old Sway Bar Links:
- Locate the sway bar links; use a socket and wrench to remove the nuts at both ends.
- Inspect the sway bar bushings for wear and replace if needed.
Install New Sway Bar Links:
- Attach the new sway bar links at both ends, ensuring they are secure.
- Torque the nuts to manufacturer specifications (usually around 30-40 ft-lbs).

4. Reassemble and Lower Vehicle

Reinstall the wheels and torque the lug nuts to the specified torque (typically 80-100 ft-lbs).
Carefully lower the vehicle back to the ground and perform a final inspection.
