both are fairly easy to check, for the tie rods, just jack it up leave the wheel on and push and pull on the front and back, if the wheel pitches to the right and left but the steering shaft doesnt moove then its the tie rods. As for the ball joints its the same situation, jack it up with the wheel still on, but put a crowbar under the tire and try to lift it. If you see either the upper or lower control arms separating from the spindle then its the ball joint. Also just check and make sure the bolts on the control arms are tight. If you need any more help you can im me or try to get in touch with one of the guys near you.
