Lift the truck again with no weight on the suspension.
Make sure the steering wheel is locked (pull the ignition key and turn steering wheel until it locks). Try to get the steering wheel to lock in a fairly strait position.
Now, one at a time, go to each front wheel, grab the tire with your hands at the 9 o'clock and the 3 o'clock position, and push/pull with your arms to get the wheel to rock for and aft (front to back). If it feels loose or you can feel play in it, try grabbing the tire at the 12 o'clock and 6 o'clock position, and try to rock it up and down.
If you can feel looseness (or play) in both tests, then either it needs a new hub (bearing) or the axle retaining nut is loose.
If you feel looseness only when you do the for and aft (front to back) test, then it has a worn out inner or outer tie rod end.
If you feel looseness only when you do the up and down test, then it has a worn out upper or lower ball joint.

Hope this helps.
