Where are ball joints located on a car?

Answer 1

Newer cars have one each side on the front, older ones and rear wheel drive have upper and lower ones. Right behind the tire, lowest piece of metal frame called lower A arm or lower control arm. At the point closest to the tire is the piviot point so that the tire can turn. Looks like a large tie rod end, and serves the same type of purpose. Most are pressed in, can usually be hammered in if you are carful. Some are riveted in from the factory and replacment ones bolt in. Grind, chisel off rivets, bolt in new.
