THE LOOSENESS CONDITION MAY BE CORRECTED BY INSTALLING THE NEW SERVICE KIT, GM P/N 10402691, AND USING THE FOLLOWING PROCEDURE. THE REPAIR CONSISTS OF REMOVING THE SEAT FROM THE VEHICLE, ADDING A PLASTIC "WASHER" TO THE RELEASE MECHANISM ON THE RIGHT SIDE OF THE FRAME (SEE FIGURE 1), AND REPLACING THE SEAT BACK BUMPER ON THE LEFT SIDE OF THE FRAME (SEE FIGURE 2).

4. INSERT THE PLASTIC WASHER BETWEEN THE RELEASE LATCH PLATE AND THE INNER SURFACE OF THE FRAME TO ACT AS A "SPACER" (SEE FIGURE 1). APPLY A LIGHT COATING OF LUBRICANT (SUCH AS GM #12346293 LUBRIPLATE LUBRICANT, OR EQUIVALENT) TO THE LATCH PLATE, WASHER AND INNER SURFACE OF FRAME TO ENSURE SMOOTH OPERATION.
