yea, the pit-man arm is keyed. Has 4 flat spots at 90 degree increments around the shaft. I had a thought for a minute that I had installed it 90 degrees off, but looking at it, it is only about 5 degrees off or so. I have all the tools to pull it easily, so that isn't an issue. I should have mentioned that. That is why I tried to take the pitman arm back. I figured the one I got was made wrong, since that is the only new part, and the rest is all off of mid 80's C10/suburban.

I could just check another brand pitman arm. That was the only brand they had at the part store and both parts were identical.

The alignment shop stated they thought it was the sector shaft, but I have been using the box for two years now and it was fine before I swapped on the new crossmember.

Is there something i could have installed wrong on the idler arm that would have it off?
