When you jack a vehicle up,the suspension all drops down and pre-loads weight on the steering linkage, springs, ball joints, etc.. If you can slide under far enough, without using a jack, to get a hand on each tie rod end, steering (Pitman arm), and reaching behind the wheels, the upper/lower ball joints. Doing these one at a time with someone flipping the steering wheel back and forth can often pinpoint the dry joint. Better yet, a cheap mechanics stethoscope really will make the job easy.

jack the tire up 3 inches off the ground. take a 4 ft 2 x 4 and put the end 6 inches under the tire pointing outward away from teh axle. lift the 2 x 4 up and down against the tire to lift the truck slightly. look at the ball joint while doing this. if it moves more than 1/16 inch, its shot. (internal slop between the stud and ball).
