1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Raise the Vehicle

Tools Required: Jack, jack stands, wheel chocks
Use a jack to lift the vehicle and secure it with jack stands.
Place wheel chocks behind the rear wheels to prevent movement.

3. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Inspect struts/shock absorbers:
- Remove the wheel to access the suspension components.
- Check for oil leaks around shocks/struts; replace if necessary.
- Torque specifications for strut mounting bolts should be followed as per the service manual.
Inspect sway bar links:
- Remove the sway bar link bolts if they exhibit wear.
- Replace with new sway bar links and torque to the manufacturer's specifications.
Inspect and replace control arm bushings if worn.

4. Final Reassembly

Reattach the wheel and lower the vehicle back to the ground.
Tighten lug nuts to the specified torque.
Conduct a visual inspection to ensure all components are properly installed.
