So the turn signal in my truck is not functioning. I am not sure what is wrong with it. The control arm is just loose in the socket and doesn't feel like it is attached to anything.

I found lots of parts on rockauto but not sure what I should buy. Also the videos I found showing how to repair turn signals show a tuning fork looking thing to get a spring off the steering column. Do I need to get one of those?

Thank you for your help. Please bear in mind that I am very new to auto repair.
