2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands for safety.

3. Inspect and Replace Components

A. Shock Absorbers/Struts

Remove the wheel to access the suspension components.
Disconnect the upper and lower mounting points of the shock absorber/strut.
- Tools Required: Socket set, wrench
Replace the shock absorber/strut with a new unit.
- Torque the bolts to manufacturer specifications (typically around 30-50 ft-lbs, verify with service manual).
Reinstall the wheel and lower the vehicle.

B. Sway Bar Links

Locate the sway bar links and check for any visible damage.
Remove the bolts securing the sway bar links to the sway bar and control arm.
- Tools Required: Socket set
Install new sway bar links and torque bolts to manufacturer specifications.
Reinstall the wheel.

C. Control Arms/Bushings

Inspect control arms for signs of wear or damage.
If needed, remove the control arm by loosening the mounting bolts.
