Did you go into a gutter sideways recently? If so, it will be a front wheel hub.
My commodore VZ is making vibrating sound but its intermittent. Some times its very smooth but some times makes load vibrating sound you can feel it more when turning steering. I recently got swaybar links replaced. But its still making that sound. I have taken to 2 different mechanics but they can't hear sound. any suggestions why its making sound?

Check the power steering oil level. It could be low causing p.s. pump cavitation - vibration??
