Duh duh dah DAAH! Done (diagnosing anyways...).
First, disconnect the battery.
Second, use tools (I prefer a ratcheting type) to remove three bolts and a nut metric sized 15. In the picture, they correspond to where they came from. And to better access the front ones, slide the seat back. And the cover on the front left one, it just pops off. You can just pull towards the front. For the back, slide the seat forward. They are a bit cramped and the right rear is a little bit of a pain to get to. I sat in the back seat for it.
Then disconnect the weight and seatbelt sensors and airbag. Just flip the gray tab and pull.
Tilt the seat to the left, grab the right rail, and lift out of the car. You will be left with a gaping hole. And in my case, my passengers will be grateful. They have room to get in the back now!
I brought my seat inside under optimal lighting and flipped it over to get a better look at what is causing this infernal clicking and movement. This is what I saw.
And after jiggling and moving of various parts, the only thing that was moving was this bar on this bolt. Problem for me is that I don't have the tools to tighten this, so I am going to have to go shopping for some Torx bits. But for me, this is on both sides and they are causing the problem.
I don't know if they are damaged, just need a new grommet, or tightening... I just don't know. But I hope this helps.
