How to fix Durango ’98 Gen I, Electric Seat Track (rocking chair effect)

We initially removed the upholstery and the bottom cushion during the initial inspection, so we could see better the full assembly. The main advantage is that we can rest the metal frame in a solid surface which makes it easier to work.
You do not have to remove the sliding steel tracks from the assembly
You do not have to remove the cushion and upholstery in order to do this job.
Description:
There is an acme tread long screw (worm gear) between the top and bottom track.
The front of the acme screw rests in a plastic bearing.
There is a gear aluminum case from which a small transmission cable attaches to the front of the worm gear; both ends of the cable have a square shape. The cable is not attached to either end. It just slides in or out of either side.
Inside between the tracks there is an aluminum case that is held in place with 2 torx screws to the track.
The problem:
Inside of the aluminum piece there is an acme thread nut. There suppose to be filler, possible made of rubber, which has been affected by the grease. You will not find pieces of broken plastic; the rubber has become some sort of asphalt with the grease.
Because of the lack of the filler between the acme nut and the interior of the aluminum casing, there is a gap which allows the seat to move back and forward like a rocking chair.
