I've recently been noticing a noise sometimes like a faint "knock" and then it goes away. Also this doesn't happen all the time so im confused. I notice it sometimes when i turn or when im stopped completely and put it into first and start to drive. I dont know what it is but it is starting to bother me

. This noise is also coming from what sounds to be under the steering wheel by my clutch. And i dont think i hear this noise after the car has been running for a while. I tend to notice it a lot more when the car is still warming up. (like when i start her up in the morning and after a day of school, like when the engine is still sorta cold i guess) So ANY help would be much appreciated!! Thanx
