Help Needed - Steering Wheel Off Center
 

I have a 2001 Suburban 2WD. I had the alignment done a couple weeks ago. Yesterday, as I was backing into a space from a 90deg angle, as I turned the wheel I heard a humming associated with the steering wheel/column. Since then, my steering wheel is cocked about 10deg to the right, but the vehicle drives straight still. Any advice is appreciated, thanks!

I'd take it back to the alignment place the wheels need to be set straight prior to aligning the steering wheel.
