Hello, inspect the cv boot on both front axles, if the boot is torn and dirt is entering the cv joint, it is a cv joint noise. If this looks ok. An inspection of the brakes and front suspension should be done, if something is loose in the front suspension it will allow the wheel to shift and cause noise concerns.
There appears to be this service bulletin to update front cv axles and to install a washer in between the axle and wheel bearing end. You can contact your local dealer to see if this applies to the build date of your vehicle.
