2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the front wheels to gain access to the suspension components.

3. Inspect and Replace Components

A. Sway Bar Links

Inspection: Check the sway bar links for wear and the condition of the bushings.
Replacement:
1. Remove the nuts securing the sway bar links using a socket set.
2. Replace with new sway bar links.
3. Torque the nuts to the manufacturer's specifications (usually around 40-50 ft-lbs).

B. Struts and Shock Absorbers

Inspection: Look for any leaks or physical damage on the struts and shocks.
Replacement:
1. Remove the upper mounting nuts from the strut assembly.
2. Disconnect the lower strut mount from the control arm.
3. Replace the strut with a new one, ensuring proper alignment.
4. Torque the upper nuts to the specified value (usually around 15-20 ft-lbs) and the lower mount to 60-70 ft-lbs.

4. Reassemble and Lower Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Torque the wheel lug nuts to the manufacturer’s specification (typically 80-100 ft-lbs).
