Control arm issue started a few months ago with a squeaky sound when I would turn the wheel

It started a few months ago with a squeaky sound when I would turn the wheel. Then it started shaking at higher speeds. Bad uneven tire wear on front. I thought it was my tires so I replaced them and had an alignment and still have a problem. My steering wheel is also crooked. It shakes really bad even at 45 mph, and when I turn left, but when I turn right or can straighten the wheel it gets better. I took the tire off the other day and looked and you can see where my lower control arm attaches to the frame under the engine block, there is a lot of play. Control arm looks good itself, just loose where it attaches. Is this the problem? Can I just change that one part or do I have to change all bushings? Thank you!
