- No, it's probably your CV (Constant Velocity) joints (since the noise

- I drove mine for about 10,000 miles. The noise kept getting worse,
- and happened even on gentle curves. I suspect if you let it go too
- long, you might snap the whole joint and the spinning driveshaft
- could do serious damage under there.
-
- When I did this, the standard repair was to replace the entire
- half-shaft (~$150 parts). The job wasn't too hard, except for
- getting the #%$!* ball joints to come apart.

- Good luck,
