Use a jack to lift the vehicle and secure it with jack stands.

2. Inspect and Replace Suspension Components

Remove Wheel:
- Use a socket set to remove the lug nuts.
- Take off the wheel to access the suspension components.
Check Shock Absorbers:
- Inspect the shock absorbers for leaks, dents, or any physical damage.
- If damaged, proceed to replace them:
  - Remove the upper and lower mounting bolts using a socket set.
  - Replace with new shock absorbers and torque bolts to manufacturer specifications.
Examine and Replace Sway Bar Links:
- Use a pry bar to apply pressure to sway bar links to check for play.
- If worn, remove the sway bar link bolts with a socket set.
- Install new sway bar links and torque bolts to specifications.
Inspect Control Arm Bushings:
- Check for cracks or deterioration in the control arm bushings.
- If necessary, remove the control arm by loosening the mounting bolts.
- Replace bushings with new ones and reassemble, ensuring proper torque.
Reassemble:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
