"Thanks for your help but I'd rather do it myself for experiance because if you never try it you don't know if you are able to do it or not." (from another of the OP's posts)
I know some may think me negative, but your approach so far leads me to the "not" side of the equation. If you are going to be successful working on your bike you can't do so by following by rote instructions and videos. From losing a ball bearing when supposedly just changing a "hub skewer" to not being able to mount a rear wheel, to ordering disc brakes before you are familiar with them, to this problem, it really appears that you either don't possess or are not using the observation and logic necessary to be able to do proper work on your bike
