To check them you need an assistant: Put your hand around the joint and hold it gently but completely, have someone rock the front wheel side to side to load and unload the joint. If you feel it knock it has play in it.
You can reach in through the suspension to check the inner ones. It's not uncommon to have one good and one bad on the same side of the bike.
I don't know about your area but here it's not possible to buy just the end, we have to buy a complete tierod assembly. If you do this, check the ends before you fit them.
For info: If you rock the wheel top to bottom you can check for top ball joint play in a similar way.
