ticking noise

Hello, I'm very new to this. This noise just started. When going in drive it makes a ticking noise but the noise seems to go away after I go over 10 miles in hour.

Could be more of a clicking noise. Could it be something not going into gear or a cv joint.

could just be sticky lifters... Or the valve seals (common)

How would I go about finding out which one it is? I am in no way a mechaniclly smart person. If I could figure out what it is causing this noise I can see if my father could help me fix it.

as stupid as it sounds try grabbing your key chain the next time that you hear the noise and see if it stops.
