Hi all. I have a late 1990s Jeep Grand Cherokee steering box in my '66 GTO. I purchased it as a remanufactured Lares unit from Rock Auto. I enjoy the quick ratio, but find it to be very dead on-center when driving down the road. So today I removed it from the car to see if it needed to be adjusted.

I loosened the preload adjuster nut on the pitman shaft, then adjusted the worm bearing to where it felt appropriate. From there, I re-tightened the pitman shaft preload adjuster nut so that it was just tight enough to remove any slop but not cause bind.

The problem is, when I adjust it so there is no slop with the pitman arm pointed straight ahead, there is slop when I move the pitmarn arm to an off-center position. If I adjust it so there is no slop when the pitman arm is off-center, it then becomes too tight to move the pitman arm back to the center position.

Am I doing something wrong here, or is my steering box defective in some way?
