If the ball joints are worn, what would the symptoms be. Could a slightly worn lower ball joint cause a reverberation back and forth in the steering wheel? It only occurs at 30-40 mph and there is no pulsation in the brake pedal. The steering is otherwise straight and trouble free. This is occurring on a 97' Chevy C-1500 2wd 305. I have replaced the shocks, upper control arm bushings, wheel bearings and race, tie rod ends (all), idler arm, pitman arm. What else could it be? The upper ball joint requires a lot of force to make it move, however the lower one moves quite easily, but is not pryable with ample force. Give me some suggestions guys.
