Hey Tyrone! I was able to fix it by opening up my controller and cleaning the sensors on the left stick. This helped me a ton.
When you get to step 11, make sure you move both the green plastic housing for the left stick's sensors. The one on the right controls the X axis and the one on the bottom controls the Y axis. You most likely need to clean out the bottom sensor with some canned air and it should work.
Saved me a few hundred bucks by not buying another controller! Hope this helps out!
