### Condition

Some customers may comment that when driving at highway speeds, a howl/bottle type noise is heard at the rear of the vehicle .

### Cause

This condition may be caused by the deck lid not contacting the seal.

### Correction

Adjust the primary sealing flange.

1. Make sure the deck is flush to the body before adjusting the primary sealing flange.

Important: Do not over adjust. This will increase the deck lid closing effort.

2. Adjust the primary sealing flange by placing a block of wood under the flange and bending it upward slightly with a hammer.
