Jack up one front wheel at a time, until the tire is 3-4" off the ground. Take a pry tool of your choice (pry bar, crow bar, jack handle, pipe, etc.) and pry upward on the bottom of the tire. Check for vertical movement of the tire/wheel. Too much movement is an indicator of excessive ball joint wear.
Now, with the same wheel/tire, place hands at 3 and 9 o'clock positions. Move tire from side to side, and check for excessive movement. There should be some free movement when doing this, but not too much. This checks steering/ hub bearing wear. You may want to have a friend do this while you watch the steering linkage. Again, some movement is expected, but not too much.
