Chuck? slipping

[josh_jahnke21]

Hey all! I am having trouble with my drill. I bought it a year ago, but lost the receipt, so I'm thinking of repairing it myself, or taking it to a service center... I haven't decided yet. Either way, I am not knowledgeable about the mechanics of drills, and am wondering what is causing this issue I am having. When I put the drill on the second speed, I hear the drill working, but it doesn't actually turn the chuck. What is causing this? What part(s) would I need to replace? At present, it still works on the first speed, and both first and second in reverse, but I am sure it's only a matter of time before those stop working as well. Thanks for your help!
