today wheni came back from the store, i puleed the car into the garage and heard this knocking noise but didnt think too much of it. later on i went to hang out with some of the other guys around town, and as i was driving home i heard the noise and i would increse as i sped up, any of you guys got an idea to what might be wrong with the car?

Where is the noise coming from? Front/ back, drivers/ passengers side?
Does it happen when you are turning left, right , both? Or maybe it doesn't happen when you turn?
Does it happen going forward/ back or both?
Does it happen when your suspension cycles? Like when you go over a dip or bump in the road?
Does the sound get louder or more frequent with speed? By speed I guess you mean car speed.

Probably something to do with your drivetrain, driveshaft, diff, half-shafts, bearings/spindles since it increases with car speed.
Do you have a limited slip? They make knocking noises.

Need more info.

its coming from the front left wheel, and i really cant tell what part is making the sound, i hope its nothing expensive. and it does it when the car is moving forward, and it does get louder and more frequent as the car speeds up

Put the car up on stands and check the suspension, spindle and hub for anything loose.

Do you feel it in the steering wheel?
