LeSabre hood shakes by sprinterpa

My 1998 LeSabre has a hood that shakes at highway speeds. It is fine near the latch, but shakes to the left and right of the latch. It is fine in the back near the hinges.
 
Are there any adjustments I can make to fix this?

There are two rubber bumpers to the left and right of the front that screw up and down. You can raise those to put a little more lift on the right/left edges of the hood.
 
You can check to see if the front center which is controlled by the latch itself can go down a little to put more downward pressure on the bumpers at the sides. There are two bolts holding the hood latch in place. I found mine were already at the bottom from the factory.
 
Assess how the hood level matches with the fenders before making larger adjustments.
 
Next thing is to question whether the front wheels are out of balance and causing a shaking vibration to shudder through the body. How are they? My hood would give little shakes when going over a bumpy road but not just traveling along. My wheels are well-balanced so they don't emit shake. I have always been sensitive about out-of-balance wheels.

Thanks for your answer! It appears that the center latch needs to move down a bit as the edges of the hood are a little higher than the fenders at this time.
 
My tires are new and balanced. It only shakes at highway speeds or bumps.
 
Thanks again for your advice!

You might check the back of the hood. I think there's a bumper in the middle of the back and also if the sides have bumpers and where the hinges are vertically.
