Bottom bracket / Crank issues? Not sure what's up.

I've got a Raleigh Sprite 10 speed, it's a 74 I think. For a while, it's had this issue where there is a little squeak when I'm pedaling. It always happens when the left side crank is at 12 o clock. Whatever the issue is hadn't really manifested itself any further, so I mostly just ignored it. Yesterday, however, I rode it 20 miles and I noticed something new. Every so often, I'd feel a little bump from my right crank at that same 12 o clock point. When it happened, it would happen for a few cranks in a row, and then it would go away for the next several miles. I noticed no equivalent sensation from the right side crank.

I'm not exactly sure what the issue could be. I might try tearing it apart later, but as of yet, I'm not even sure if I have the tools I need for the job, so I figured I'd ask here, where people are more knowledgeable than myself, and see if anyone recognizes what's going on.

If anyone needs any further information, let me know.

Rebuild of the bottom bracket is probably in order.
