Some 1985-1991 M/L vans may experience 2nd and 3rd bench seat squeaks or rattles. These conditions may occur if the seat spring rubs against the frame rail, front frame retainer tab or rear frame capsule.

To correct, it is necessary to apply a liberal amount of teflon base lubricant (GM Part Number 12345718) to the ends of the springs.

SERVICE PROCEDURE

1. Remove the seat and position upside down.

2. Without disengaging the springs, manually slide all the springs (one at a time) as far as possible to one side.

3. Using a small grease brush, liberally apply lubricant (GM Part Number 12345718) to the capsule and spring ends and at all points where the spring contacts the rail (see Figures 1 and 2).

4. Without disengaging the springs, manually slide all the springs (one at a time) as far as possible in the opposite direction.

5. Using a small grease brush, liberally apply lubricant (GM Part Number 12345718) to the capsule and spring ends and at all points where the spring contacts the rail (see Figures 1 and 2).

6. Reposition the springs in the center of each capsule.

7. Lubricate the front rail/spring contacts by pushing the seat foam pad away from the rail. Using a small grease brush, apply a small amount of lubricant to the spring end in the retainer tab/rail area (see Figure 3).

8. Clean excess lubrication.

9. Reinstall the seat.
