2. Lift the Vehicle

Using a jack and jack stands, lift the front of the vehicle.
Ensure it is securely supported before proceeding.

3. Inspect Suspension Components

Sub-steps:
- Visually inspect control arms, struts, and bushings for wear or damage.
- Check the ball joints by attempting to move them up and down with your hand.
Tools Required: Flashlight, pry bar.

4. Check Wheel Bearings

Sub-steps:
- Grab the wheel at the 12 and 6 o'clock positions and shake it. Any play indicates worn bearings.
- If play is present, remove the wheel and inspect the bearings for wear.
Tools Required: Socket set, torque wrench.

5. Examine Driveshaft and CV Joints

Sub-steps:
- Inspect the driveshaft for any visible damage or loose connections.
- Check the CV joints for torn boots or excessive movement.
Tools Required: Pliers for boot clamps, socket set.

6. Reassemble and Torque

Sub-steps:
- If any components were removed, reassemble them.
- Torque all suspension and steering bolts to the manufacturer’s specifications (typically around 80-100 ft-lbs for control arms).
Tools Required: Torque wrench.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle to the ground.
