I have an '03 Sierra 4X4 Z71, and had a shop replace the Pitman and idler arms, along with my inner and outer tie rods. I also had my steering box removed to both fix a small leak and "rebuild it", at least that's according to the shop. The problem now is that the steering wheel isn't just out of alignment, it feels like the trucks WANTS to go to the left. I've driven cars with misaligned steering before, but I feel like this one is fighting me to steer to the left, so I have to actively put pressure on the steering wheel and steer it slightly to the right to make it go straight down the road. And when I let go of the steering wheel, it slightly moves to the left on its on as if it feels more comfortable this way. The alignment shop told me that everything is within spec, except that my control arm bushings are slightly worn out. The steering WAS straight before I had done the job. I'm suspecting that it has something to do with the steering box since it was removed, but I can't find much info on my specific problem.
