My Impala makes metalic clicks at slow speed on turns especially on bumpy surfaces.

IS it on the left or right?
-Have someone stand outside the car while you pass them to confirm this. It can be illusional from the inside of the car.

Does it follow the wheels RPM? Or is it independent of the wheel rotation?

Does it change turning one way or another, going straight, or veering?

IT does not do this on smooth surfaces?

IF it is independent of the wheel rotation, I would be thinking the verticle mount of the lower control arm or stabilizer links.

IF it follows the rotation it can be a wider variety including axle, brakes, wheel bearing.

Need more info on this.

No, the sound does not correspondence to the speed of the wheel rotation. The sound is on the passenger side of the car.

I took off both wheels and both of the disc brakes are in good condition.

The sound is more pronounced at slow speeds, especially when turning and some times as you go slowly over a speed bump which Sacramento has many of on the suburban streets.

We are visiting our son in Colorado and he lives on an acreage with a dirt drive way that exit onto a paved street. When turning on to the paved street (a little rise from the gravel drive the metalic clicking sound is pronounced on the passenger side of the car.

It does not do it at high speeds on the highway or smooth surfaces.

Check the verticle mount of the lower control arm and stabilizer links.

Try to duplicate the nose by pushing up and down on that corner of the car. Don't be afraid to jostle it good. That may aid in finding the source.

Also check the spring to make sure it isn't broken. Other possible sources would be the low ball joint, strut mount, outer tie rod end. The stabilizer bushings that the stabilizer bar is held to the body with may have movement as well.

IF you aren't sure how to check these, let me know.
