I started to notice a couple days ago when I get to speeds of 50mph that my left wheel/wobble started to shake and it would feel if I had a flat tire. I took off my tire today and my steering knuckle is loose, the ball joint is fcuked too, needs replacement.

it looks to me like this is the part i need and I can just attach the new joint to the existing knuckle and this issue will be rectified. NAPA AUTO PARTS

Is anyone able to confirm?

I got that from the chilton\online service manual . I guess the underlying question was can i just replace the upper ball joint or would I need to replace the entire upper control arm?

If it is loose, replace the upper control arm. That is what your link to napa shows.
That link shows the entire upper control arm, they also just sell the upper ball joint. Which leads me to believe I could possibly just replace the ball joint. The price of the parts arent the issue, I guess which would save more time and be more effective for the future. Logically if I just need to replace the upper ball joint and keep the existing upper control arm and steering knuckle then that sounds like the way to go, but if its recommended i should just get the entire upper control arm that comes with a new ball joint and just hook it up to the existing steering knuckle then i'll probably do that.

The other part that wears out on the upper control arms are the bushings on the pieces that go into the engine compartment. They often are worn out making replacing the whole piece better. If you are able to replace only the ball joint and not have to pay someone to do it for you, then you can go that route too.
