2. Inspect and Replace Suspension Components

Inspect Shock Absorbers:
- Remove the wheel to access the shock absorber.
- Check for any leaks or significant wear. If damaged, replace with new units.
Replace Sway Bar Links:
- Locate the sway bar link attached to the sway bar and the control arm.
- Remove the bolts securing the sway bar link using a socket wrench.
- Install the new sway bar link and torque to the manufacturer's specifications.
Check and Replace Control Arm Bushings (if necessary):
- Remove the control arm by unbolting it from the chassis and the ball joint.
- Replace any worn or damaged bushings with new ones, ensuring proper alignment during installation.

3. Reassembly

Reinstall all components in reverse order of removal.
Ensure that all bolts are torqued to the manufacturer's specifications.
Reattach the wheel and lower the vehicle.
