I hear a noise everyday when i back out of my driveway or really ever now and then when i back up. i also hear this ever once and a while when i go straight. it sounds like something thunking in the front end and my wheels are almost always turned when i hear it. i greased my steering stops and that's not it cause i don't have to have my wheels tirned all the way to hear it. my dealer tells me they don't hear it but i do. please help me. thanks. curt73@aol.com
