Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and a flashlight.
Ensure the vehicle is on a flat surface and securely elevated with jack stands.
Disconnect the battery to avoid any electrical issues.

2. Inspect Suspension Components

Remove the front wheels using a socket set.
Visually inspect control arms, ball joints, and bushings for signs of wear or damage.
Use a pry bar to check for play in the joints; if any joint moves excessively, it needs replacement.

3. Check CV Joints

Inspect the rubber boots of the CV joints for cracks or tears.
If the boot is damaged, replace it and the joint if necessary.
If the noise persists, consider replacing the entire axle assembly.

4. Examine Wheel Bearings

Rotate the wheel while listening for any grinding or roughness.
If play is detected, remove the hub assembly and replace the wheel bearing.
Ensure to torque the new bearing to manufacturer specifications.

5. Inspect Sway Bar Links

Check the sway bar links and bushings for wear.
If damaged, remove the old links and install new ones, ensuring they are torqued to specifications.
