Park the vehicle on a level surface and engage the parking brake.

2. Lift the Vehicle

Using a hydraulic jack, lift the front of the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Remove the wheel to access the suspension components.
Visually inspect the struts, control arms, and bushings for any signs of wear or damage.
Check the sway bar links for looseness or broken parts.
Use a pry bar to test the play in the control arms and bushings.

4. Replace Damaged Components

If any worn or damaged parts are identified, replace them as follows:
- Sway Bar Links:
  - Remove the old link by loosening the bolts with a socket.
  - Install the new link and torque to manufacturer specifications (usually around 40-50 ft-lbs).
- Struts or Shocks:
  - Remove the strut assembly by loosening the top and bottom bolts.
  - Replace the strut or shock with a new unit and torque bolts to specifications (usually around 30-35 ft-lbs for top bolts and 70-80 ft-lbs for bottom bolts).
Reinstall the wheel and lower the vehicle.
