Latley my power steering pump has been whining (they all do) I have been going to replace it but haven't gotten around to it. While driving last night I went to turn and it was like my steering column or what not got caught on something and broke right free and made a slight "klunk" noise (faintly). It wasn't like I lose power steering it was like a mechanical thing, now it is doing it like crazy all the time it doesn't stick really bad but it is bothering me and I don't want it to lock up and stop me. I just wanted to know if anyone else has had this problem and what it is???? Thanks!
