Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.
Tools required: jack, jack stands, socket set, torque wrench, pry bar.

2. Inspect and Replace Worn Suspension Components

Inspect Struts and Shocks:
- Check for oil leakage or physical damage.
- If damaged, remove the old struts/shocks by loosening the mounting bolts and detaching them from the vehicle.
- Install new struts/shocks and torque to manufacturer specifications.
Check Sway Bar Links:
- Inspect sway bar links for wear; if damaged, remove them by unbolting from the sway bar and control arm.
- Replace with new sway bar links and tighten to specified torque.
Inspect Control Arms:
- Look for worn bushings or any play in the control arms.
- If bushings are worn, remove the control arm by unbolting it and replace with new bushings or a complete arm if necessary.
- Torque to manufacturer specifications upon reinstallation.

3. Final Assembly

Recheck all components for proper installation.
Lower the vehicle and ensure all fasteners are tightened according to specifications.
