Vehicle has a low frequency growl or grinding noise, that phases, and emanates from the right front.
The noise also seems to manifest in a vibration that can be felt as well. Although present when steering straight it is pronounced on a left turn, and not noticeable on a right turn. Speed does not seem to be a factor although it seems more prevalent at low to mid speeds.
We placed the vehicle on jack stands, started, placed it in 4wd to get the front wheels to turn. If you hold the left, forcing the right to rotate the noise is noticeable, again more so on left turn. Definitely not as pronounced as when the vehicles weight is in place. If you hold the right front forcing the left to rotate the noise is eliminated.
Brake pads and rotors are essentially new, CV Boots are undamaged.
Don't see how it would be a final drive noise since it is affected by steering wheel inputs.
We suspect front hub, bearing, or possibly CV joints?
Need to know if one of your experts has an answer, or a suggestion on how to further diagnose?
have the same problem?
