Left analog sticking any solutions?

kenny, the first thing I suggest is that you clean it properly. Follow this guide to work on it. Remove all the buttons and rubber pads they are sitting on. It is a good idea to lay them out on the floor or table, what ever you are working on, in the same pattern as they go in your controller. Makes it easier when you are trying to figure out what color goes where. You could also draw yourself a diagram before you remove the buttons.

You will probably notice that the board and buttons are sticky. Wash all the rubber pads in mild soapy water. Dishwashing soap works well. If the board is really bad wash it too. If it does not look too bad you can get some cotton swabs and some rubbing alcohol and clean the contacts that the rubber pads were sitting on.

Make sure everything is completely clean and dry. Turn your top cover over and start replacing your buttons. They should be keyed so they can only go in one way. Next put the rubber pads back in place on top of the buttons. At this point you still have the top cover inverted.

Re-install the bottom cover and install the screws. Check your buttons to make sure they all move freely. Here is more info and pics as well.

If that does not resolve it, I would suggest to replace the stick with a set of new ones. They are relatively inexpensive and it only requires basic soldering skills to replace them. You can also try to reflow the solder connections of the joystick. If that does not resolve it, it may be time to replace the controller. They are available on places like this. On the how-to part, here is my answer from a similar question. "use this as a general guide. All you need to do, is to unsolder the connector and solder the new joystick in place. It should be a straight forward repair. Of course, you'll need a soldering iron, a desoldering wick (or solder sucker, flux and solder to repair the joystick...Hope this helps, here is a great tutorial. Hope this helps, good luck.
