They selling new control arms for $50-$100 each on rockauto however isn't it serviceable, can i am certain i can take old control arm replace bushings and ball joints and put it back?

If so where do i buy correct bushings and ball joints for 1998 explorer sport rock auto does not seem to sell them separately?

 

I don't know of anyone that sells them separately. The lower one comes with the ball joint already in it.

 

It has ring to remove it, is there anywhere i can buy new ball joint for lower control arm?
