I'm new to this forum. I just picked up a TJ with a 2" lift and 33"BFG's. There is a dead spot in the steering for 11-1 o'clock. I got under it and had a buddy turn the wheel back and forth in the dead spot. The steering column shaft is moving going in to the box, but the pitman arm isn't moving coming out. It seems to me the gears are worn and the box needs to be replaced. I tried adjusting the allen screw on the top, but all that did was make the steering tighter and the Jeep drift across the lane. I just want to make sure this is the problem before I start putting new parts on.
for a temporary fix you can tighten up the steering gear, on top of the gear there is a locking nut and an adjustment screw, loosen the nut, tighten the screw, when snug back it off about 1/8 to a 1/4 turn and tighten down the nut, it isnt a permanent fix but it will help, the steering gear will continue to wear out, but it will increase the drivability until you can get a gear box for it.
