I haven't replace any steering part yet but I had time to try to tshoot and isolate the issue further today.

So when I wiggle the steering wheel back and forth ever so slightly and put my hand under the dash and hold the steering shaft, I can definitely feel something clunking very slightly. I went under the car to feel the joint near the steering rack while my son wiggled the steering wheel. I can feel it there but I don't know the clunk is radiating from somewhere up the shaft. Watching the joint it doesn't seem like there isn't any play.

I took off the cover under the dash that covers the join there. I feel like the sound might be coming from there and while holding the joint under the dash while wiggling the wheel, I can feel the clunk too. I feel like it is coming from somewhere there. I saw the post about the rubber isolator and someone replacing it with a steel spacer. Not sure why a rubber isolator would cause the clunk. There doesnt seem to be any visable play at that joint either.

Is it possible it could be something more towards the steering wheel inside the steering cover?

I'm going to try shaft slide yoke trick to see if that fixes it in the mean time.
