If your seat is moving side to side, the seat base is broken.
Look under the rear bottom of the seat with a mirror,
and you will see the brace that runs from track to track.
It will be broken on either side where it bends to meet the tracks on either side.
Mine broke TWICE before my dealership got one that would hold permanently.
It starts with a squeak, then moves, side to side,
and then the recliner breaks off the seat back.
Not something you want to have happen.
