Mine was doing something like this a few years ago when I had similar work done. I can't remember which part of the tie rod it was... one of them was not tightened down enough, and caused a popping/clunk sound. Wish I could be more specific, I just don't remember. I do know that I drove on it for a few weeks (not driving everyday) trying to figure it out. This caused an entire tie rod, inner and outer, to be replaced. Eventually, I was able to jack up the entire front end and wiggle the driver side Tire left and right without moving the passenger side Tire. It made steering a little interesting... and then back to Firestone for an alignment. Love the lifetime alignment.
