Well, pulled the seat out today that had a slight rock in it, and started in to do the "seat fix". What I found was an in-tact rubber surround around the threaded block. No open gaps at all, on either slide. I guess I need to dig a bit deeper.

On the plus side, to help (or 'hep) others, just a few pointers:

Although easy, the plastic ***** do not need to come out. I took them out the first time, noticed an adjustment I had to make and could remove the threaded rod without taking out the *****.

That adjustment being...the threaded block position on the rod upon putting it back together. One track way off! Had to take it apart and run it back to where it belonged (verified by a quick tape measure). So make sure to notice where the block is suppose to be on the rod. Don't want your seat to run sideways on you!

The screws for the threaded block on the side nearest the door (of the drivers seat) are under a metal piece that the wiring hooks to. Just pull up in the middle and the ears will pop out on the ends.

The torx bit size of the threaded rod hold down bolts are the same as the C4 removable top. I am guessing around a t40 or so, but didn't have that item on hand..only the top wrench from our C4 could be verified once the bolt was removed with vice grips (note to self, buy torx bit and new bolts)

Hope this helps someone else working on this fix. BTW, this all applies to my 2K, your vehicle may differ.

 

Thanks for the tip. If I ever have to go in this will be nice to know.
