2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Shock Absorbers

Tools Required: Socket set, torque wrench
Remove the wheels to access the suspension components.
Unbolt the top and bottom of the shock absorber.
Replace with new shock absorbers, ensuring proper alignment.
Torque the bolts to manufacturer specifications (typically 15-20 ft-lbs for the top, 35-45 ft-lbs for the bottom).

4. Inspect and Replace Sway Bar Links and Bushings

Check sway bar links for wear or looseness.
Disconnect the sway bar links from the sway bar and control arm.
Replace with new sway bar links and bushings as necessary.
Torque the bolts to specifications (generally around 30-40 ft-lbs).

5. Examine and Replace Control Arms (if needed)

If control arms show wear, remove them by unbolting from the chassis and wheel hub.
