Solution

1. Preparation

Tools Required: Floor jack, jack stands, socket set, wrench set, torque wrench, pry bar.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged. Disconnect the battery if necessary for safety.

2. Inspect and Replace Struts

Sub-steps:
1. Lift the vehicle with a floor jack and secure it on jack stands.
2. Remove the wheel on the side where the strut is being replaced.
3. Use a socket set to unbolt the strut from the steering knuckle and the top mounting points.
4. Carefully remove the strut from the vehicle.
5. Compare the old strut with the new one for compatibility.
6. Install the new strut, securing all bolts to the manufacturer's torque specifications.

3. Inspect and Replace Sway Bar Links

Sub-steps:
1. Locate the sway bar links; they will connect the sway bar to the control arms.
2. Use a wrench to unbolt the sway bar link from both the sway bar and control arm.
3. Inspect the bushings for wear; if any cracks or significant wear are found, replace the sway bar links.
4. Install new sway bar links and tighten them securely.

4. Inspect and Replace Control Arm Bushings

Sub-steps:
1. Locate the control arms and check the bushings for cracking or excessive wear.
2. If replacement is needed, unbolt the control arm from the chassis and the steering knuckle.
3. Use a press or appropriate tool to remove the old bushings and install new ones.
4. Reinstall the control arm and torque the bolts to the specified values.
