Might be the same thing that I got into, no real safety issue just an annoyance.
If it's similar to mine, was just the lower steering rod, the part that actually telescopes when you move the steering wheel.
You need to replace or re-grease this:

re-grease will only last a while to get rid of the annoying clunk
it's not all the difficult to replace. I re-greased mine when I first picked up my car just to make sure that's what it was. Came back in 7k. I'll replace it someday but it doesn't bother me much.
IIRC GM had a long standing problem similar to this in the 00's.
