2001 Kia Optima - Train sounding noise underneath

When I am driving my 2001 Kia, I hear a very loud clickety-clackety noise from underneath. It appears to be coming from the rear. It is not the sound of grinding rotors or anything like that. It reminds me of the sound the train makes when riding over the railroad tracks. I am not sure if it is the axle or what? Any suggestions?

Sounds like the bearings are going out in the rear hub(s). Drive the car for a few miles (if it is safe to to do). Park it and check to see if the wheels are warm, or even hot, in their center cap area. This will indicate excess friction from bad bearings. Replace the whole hub. It's an easy DIY job, if you are so inclined. Part cost should be just over $100. per axle. Shop around to find a good price. I recommend Timken hubs. best of luck.
