What is makeing my left front wheel feel like it sways or might fall?

When i drive my Avenger pulls to the right alot but yesterday it seamed to have pulled hard to the left instead. So i adjusted pressure and put spare on till i got home. I put tire back on b4 driving and noticed alot of maybe bouncing in the wheel at the front left tire and alot of noise like loose brakes or something maybe but it felt like my tire was gona come off of the hub asslembly or something. I dont know what happened.

Also on my front left asslembly i only have 3 outa 5 lug bolts. 3 month old brakes pleanty of fluids thruout car. Ball joints look bad i believe..
