Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, pry bar, and safety glasses.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electronic suspension components.

2. Inspect and Replace Worn Components

Check Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Inspect for leaks or physical damage.
- If damaged, remove the strut by unbolting it from the top mount and lower control arm. Replace with a new strut.
Sway Bar Links:
- Locate the sway bar links and inspect for wear and separation.
- Remove the bolts securing the sway bar links using a socket set.
- Replace with new sway bar links and torque to manufacturer specifications (typically around 30-40 ft-lbs).
Bushings:
- Inspect control arm bushings for cracking or deterioration.
- If worn, use a pry bar to remove the old bushings and press in new ones.

3. Reassemble and Test

Reattach the strut and sway bar links, ensuring all bolts are torqued to manufacturer specifications.
Replace the wheel and lower the vehicle.
Reconnect the battery if previously disconnected.
