Poll Title: Two technicians are checking a ball joint for radial and axial movement.
Technician A says if the lower ball joint is the loaded joint, a jack should be placed under
the lower control arm to relieve the load from the joint. Technician B says if the upper ball
joint is the loaded joint, a spacer should be placed between the upper and lower control
arms and the jack placed under the frame. Who is right?
