CLEANING AND INSPECTION

Rattle Elimination

Foreign objects such as nuts, bolts or small pieces of body deadener in the door wells, pillars and quarter panels, are often the source of rattles. Door wells can be checked by carefully striking the underside of the door with a rubber mallet.

All bolts and screws should be inspected periodically. In the event that tightening the bolts and screws, located on such assemblies as the doors, hood, and tailgate, does not eliminate the rattles, the trouble is probably caused by misalignment. If this is the case, follow the adjustment and alignment procedures for these assemblies.

Rattles and squeaks are sometimes caused by weatherstripping and anti-squeak material that has slipped out of position. Apply additional cement or other adhesive.
