Why does my Ford Focus make a grinding noise when turning?

I just bought a used Ford Focus and noticed that it makes a grinding noise whenever I turn the wheel. What could be causing this and how can I fix it?

It could be due to worn-out wheel bearings. I suggest getting them checked and replaced if necessary.

Check the power steering pump for any issues. It may need to be re-greased or replaced.

This could be a sign of a damaged CV joint. Have a mechanic inspect it and replace if needed.
