Suspension noise

Does anyone with a 17 Sierra hear a loud bang if they are close to full lock (turn) and try to drive forward or reverse? This is easily replicated if you are either backing out of, or pulling into a parking spot that requires you to turn the steering wheel to almost full lock. Dealership said its normal, but I am not buying that. The sound is similar to a failing CV joint, but instead of a click, click, it's a loud TONK which can be felt in the pedal.

It's the front cross member that is removable.....There is a TSB for it because I had the thud and after telling Dealer the THUD must stop!  They took care of it.....I had exact problem only on hard turn especially driveway etc. like a hammer hitting under the pedals....

That's exactly what I'm experiencing. So the issue is the cross member? Cracked, weak? Either way i will check the TSB and revisit my dealership. Thanks a lot.

It's the Bolts and not being tight on the front cross member is all!  You can do it yourself but I had dealer do it......also go under your rear leaf springs and turn those nuts around 1X too!
