Just back from a trip to Utah. Truck ran great, got ~22-23 mpg overall. We did some minor off road trails, none of which required 4WD and none of the trails had anything that could have bent, bashed or damaged anything. On the way home, I noticed the steering wheel Off center to the right. Prior to this it was perfectly centered. (pic attached) There are no indications of anything wrong. No shimmy, shake or vibration. Steering tracks true (1/2 mile w/both hands off the wheel stayed in lane) No new or unusual noises. Before I take it to the alignment shop what should I check?
