Knocking sound near tire

There is a knocking sound when I drive it. It sounds like it is coming from the passenger side rear area. It has been doing this for a while. You can't really hear it when you are driving faster, but it is pretty loud and noticeable when driving around 5 to 20 mph.

I thought that maybe the parking brake is hanging up, but when I pull the brake lever when the car is moving, the sound is still there.

It sounds like something is hitting every time the wheel spins around. I think it goes faster when you drive faster. Could it be the drive shaft or something in the wheel?
