I noticed this morning my tire was at an angle so I decided to look under and see why it was and found this. Is that part replaceable or should I just weld it back into place?

 

I don't think it is "replaceable."

Looks like it has been broken on one side for a while.

You can likely weld it as long as the metal is sound. But you really need to get back exactly where it was or you'll never get the alignment right. You also want to make sure that you get a nice weld on it. You don't need it failing again.

I'd start with a frame shop but before you do that, what's the rest of the suspension look like?

 

The rest of the suspension looks fine I just replaced the upper and lower ball joints on the passenger side I have noticed a bit of a wobble when I brake for a while now it's been at least 3 weeks but I thought it was due to my rotors which is why I didn't really give him much thought
