I don't need the ball joints yet, but have been searching, and hard to find. I've seen people say the dealership sells them with the rear knuckles, and no part number to buy them seperate. Is that the case?

 

I don't see any ball joints in the rear. Do you mean the sway bar links or the lower control arm assembly?

It looks similar to this. I replaced the sway bar links, and control arms already. It attaches to the rear knuckle at the bottom.

 

Looks like it's comes with the rear carrier sub assembly as you suspected.

Thanks for the reply. That's just dumb though you can't buy the ball joint. I did search the part numbers on ebay, and found ball joints for the knuckles, but coming from Australia so if I need them I'd probably go that route. Its about $100 shipped for 1, but still cheaper than replacing the knuckles. https://www.ebay.com/itm/176066976275
