lower control arm pivots

You can go to advance auto and rent a ball joint instal tool. Just a big c-clamp with a open cupped end. I use that to remove and install all the bushing for upper and lower arms. I use a long punch in place of it's swivel end to remove the stud. A socket to remove the rubber and a sawzal to remove the inner metal. I have used a sawzal and zip wheel to remove the metal sleeve from the pin.
