Rattle, Pop, Clunk, Oil Canning Noise From Left Front of Vehicle (Dimple/Distort Left Front Upper Inner Frame Rail Panel, Inspect Torque Specifications, Adjust Hood)

Some customers may comment on a rattle, pop, clunk or "oil canning" noise coming from the left front of the vehicle while driving over specific road conditions.

Follow the service procedure below to correct this condition.

1. Place your hand between the battery and upper inner frame rail panel at arrow above. Push outwards on the upper inner frame rail panel and inspect the panel for noise condition. It may be necessary to place a pry bar inside of upper frame rail and push inwards on the upper inner frame rail panel to duplicate the noise.
2. Remove the battery from the vehicle. Refer to Battery Replacement (SI Document ID #861594).




Notice: 

•	DO NOT USE a metal faced hammer to dimple/distort the upper inner frame rail panel metal. A metal faced hammer may damage the painted surface of the frame rail.

3. Dimple/distort the upper inner frame rail panel with a rubber dead blow hammer at the location shown above.
4. Reinspect the upper inner frame rail panel for noise. If noise condition persists, repeat the previous step.
