DO I NEED THE 4" DONUT WHEEL THAT WAS ATTACHED TO THE MIDDLE OF THE FRONT DRIVE AXLE? WHAT WAS IT FOR?

2004 Kia Rio • 322,000 miles

In doing an oil change I noticed that in the middle of the front drive axle, there was a small rubber wheel dangling from the middle of the axle, worn with age and it sheered off.

That's to dampen driveline vibration. As the car ages, the springs and engine mounts will start to sag. That changes the angle of the half shafts / cv joints, and changes the characteristics that can set up those vibrations. If you remove that weight, there's a very good chance you will not notice any vibration.
