I just had an alignment and a tire rotation a couple months ago. Today, the steering wheel is turned to the right to the 12:30 position and the car still goes straight, and doesn't pull. I tested this on city and highway roads at speeds up to 70mph. The steering doesn't feel loose nor do I hear any sounds. What is causing this?

 

Tire pressure, worn or bent steering or suspension components, misalignment... Could be any of those
