Solution

1. Preparation

Gather tools and parts needed for repair.
Safety warning: Ensure the vehicle is on a flat surface and secured with wheel chocks.

2. Inspect and Replace Components

A. Struts and Shocks

Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Disconnect the Strut: Remove the bolts securing the strut to the lower control arm and the top mount.
Inspect the Strut: Check for leaks or damage. Replace if necessary.
Install New Strut: Position the new strut in place and secure it with the bolts. Torque to manufacturer specifications (typically around 40-50 ft-lbs).

B. Sway Bar Links and Bushings

Remove Sway Bar Links: Use a wrench to disconnect the sway bar links from the sway bar and lower control arm.
Inspect Bushings: Check the condition of the sway bar bushings. Replace if cracked or worn.
Install New Links/Bushings: Attach new sway bar links and bushings, ensuring they are tightened to proper specifications.

C. Lower Control Arm Bushings

Remove Lower Control Arm: If bushings are worn, remove the lower control arm by unbolting it from the subframe and the steering knuckle.
Replace Bushings: Press out old bushings and install new ones, ensuring they are properly seated.
Reinstall Control Arm: Attach the control arm back to the vehicle and torque bolts to specifications.

3. Reassembly

Reinstall the Wheel: Place the wheel back on and secure it with lug nuts. Torque to manufacturer specifications.
Lower the Vehicle: Carefully lower the vehicle off the jack stands.
