Just a tip your indicator should never be clamped to the control when check ball joints should be clamped to stud on caliper or another suspension component

I'm reading the section for ball joint inspection on the Ford Fusion and it says DO NOT USE ANY TOOLS to pry on the suspension components when checking ball joint deflection or suspension damage may occur. they want you to use an assistant to push the control arm up and down while you measure the deflection.

From the service manual:
"NOTICE: Do not use any tools or equipment to move the wheel and tire assembly or suspension components while checking for relative movement. Suspension damage may occur. The use of tools or equipment will also create relative movement that may not exist when using hand force. Relative movement must be measured using hand force only."

What happens if there is to much play? Will it shake like when the brakes are warp when braking?

So I'm taking my inspector test for MD, I have a few people saying different things hook it to the frame bolt, seen hook it to the caliper bolt, my college book says control arm.. which is how I have been taught in college. McPherson strut type. What annoys me the most, it seems there are different ways and not everyone agree's one way. It is totally dependent on who you ask and how they see it. Who is correct? as long as it accurately measures the movement I don't see what's wrong with caliper bolt or control arm as long as one is on one and the other the other. the frame bolt guy don't make sense, he is saying it keeps the control arm bushing having play from effecting it when to me it seems the opposite would be true if you have it hooked to a frame bolt. I just want to do it the correct way, and pass my test, and do what is expected of me.
