I have a 2000 Ram 2500 V10 4x4, and I had the tie rod ends and ball joints replaced. The truck still wanders while going down the road, so I had a buddy move the wheel while I watched underneath, and it appears the steering gear is loose. The steering shaft moves quite a bit before making the pitman arm move. Is the gear something I can adjust/tighten, or does it call for replacement? And how hard is it to remove?
