Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery if working on electronic suspension components.

2. Inspect and Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, pry bar, jack stands, impact wrench (optional)
Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access the suspension components.
3. Inspect the struts/shocks for leaks or damage. If found, replace them:
  - Remove the bolts securing the strut assembly to the knuckle and upper mount.
  - Replace with new struts, ensuring to torque bolts to the manufacturer's specifications.
4. Examine control arms for wear. If bushings are cracked or worn, replace them:
  - Remove the control arm bolts and replace the bushings or the entire control arm as necessary.
5. Check ball joints for play. If they are loose, replace:
  - Remove the wheel hub assembly if necessary to access the ball joint.
  - Use a ball joint separator to remove and replace with a new one, torquing to specifications.

3. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Ensure all bolts are torqued to specifications.
Test drive the vehicle to confirm the noise has been resolved.
