2007 KIA Rondo, Cost of replacing suspension parts (arm, spring & damper) on 2007 Kia Rondo

I hear a sound like pounding something when I drive on the unsmooth road. Is it possible to get suspension parts of Rondo? Is it possible to replace one of the parts separately? For example, if the damper has broken, is it possible to replace the damper only?
