47-55.1 Steering geometry question

[TX3100Guy]

While I'm waiting on my engine re-re-build, I began chasing other minor issues that I've noticed. One of the issues involved the steering stabilizer that I installed a while back. In the few short rides I took in the truck prior to realizing that the engine needed re-built, I thought I noticed that the truck could turn a tighter turn in one direction than the other. At the time, I made a mental note to check the stabilizer to ensure I hadn't installed it in such a way as to prevent a full lock to lock turn.

Today, I jacked up the front axle and first did a full turn of the steering wheel to the left. At that point, I noticed that the drivers side wheel appeared to be turned further to the left than the passenger side. Then I turned the steeling wheel to the right fully and noticed that the passenger side wheel appeared to be turn further to the right than the drivers side wheel.

Am I imagining things? Is this normal behavior? If this isn't normal behavior, what could/would cause it?
