Inspect Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Check for oil leakage and physical damage.
- If damaged, replace with new struts/shocks.
Replace Sway Bar Links:
- Locate the sway bar link on both sides of the vehicle.
- Use a wrench to remove the bolts securing the sway bar link.
- Install new sway bar links and torque to manufacturer specifications.

3. Replace Control Arm Bushings (if necessary)

Remove Control Arm:
- Remove the wheel and brake components if necessary to access the control arm.
- Unbolt the control arm from the chassis and the wheel hub.
Replace Bushings:
- Press out the old bushings using a bushing removal tool.
- Press in the new bushings and reinstall the control arm, torquing to manufacturer specifications.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Reconnect the battery if it was disconnected.
