05 F 250 4x4, my right side lower, what I would call tie rod end, got some play, need to order a new one but don't want to sound stupid not knowing what to ask for as it seems from a quick look these trucks have upper and lower tie rod ends, or is one a tie rod and the other center link !?!?!?!? Confused !!

 

ball joints are upper and lower and tie rods are inner and outer. tie rods control toe and ball joints control camber/caster

 

These are not ball joints, they are just below the tie rod ends, on the big lower bar which I think is a center link, there is one on each side, not inners and outers like the tie rod ends, looks like a big version of the tie rod end facing up, instead of down.
