Swivel seat wobbles?

So I have the typical fixed base drivers seat and swivel base passenger seat.
We've fitted Scheel-Mann seats as the OEM balance balls were flat horrible.
The drivers seat is solid as an anvil and doesn't wiggle a bit.
The passenger seat is a wobbly mess, and was prior to the seat upgrade.
It's primarily an issue on any road that not a sheet of glass and makes my wife nuts with the constant fore-aft wiggle.
I've disassembled the swivel base and checked for broken, loose or otherwise problematic parts, finding none.
When I reassembled it, I greased everything and torqued the castle nut to what felt a "proper" 55# feet. It's as tight as I care to make it and is still wobbly.
I've diagnosed it thoroughly and there's NO doubt that the movement is in the swivel base.

Has anyone managed to cure this?

Check for play in the swivel latch mechanism. That's where my same problem was. I had a local welder fix it.

Is this a seat base from Ray/1der or a Sportsmobile original, or unknown?

I've had play in the seat slides Scheel-Mann provided before. Are they still tight?
