1999 Pontiac Grand Prix Groaning noise from front end

When I start the car and initially move it (which generally requires me to steer the car), I hear a groaning noise from the front end. The sound is like a muffled knock or "tock" sound (not a sharp metal-on-metal). The other way to describe the noise is a louder version of someone cracking their knuckles.

I recently had to pass a vehicle inspection for this car in MA. The only things that failed are the RF wheel bearing and RF outer tie rod. I replaced both, and also did the LF outer tie rod while I was at it.

However, the noise has not gone away.

Any clue as to what might be the cause? Or any other tests I can perform to confirm a cause?

Thanks
