X1C making periodic grinding noise on both up and down movements. Only while moving down there is this crackling noise.

I cleaned the rods of all plastic. I have cleaned & re-lubed the rods. I greased the pulley on the bottom and the edge of the belt.
It’s not the beds wire at the back. I held that up while the bed moved down.
Anyone have any similar issues?
