i'm a newbie... my 08 C5 had this issue this summer. i had the dealership replace the steering rack but of course that alone failed to stop the leak, it went back twice more for them to replace the hoses and seals - they did the hose replacement at no cost to me. so the leak is stopped but now when a turn the steering a bit sharply to the right I can hear a fairly quiet moan from the steering. not sure what to do about this - could it be too little or too much power steering fluid or might it be a rusty input shaft? i don't generally work on cars so i'm not even sure where to find the floor bung that people are referring to here - any advice would be appreciated
