Hollow Fender what to fill?

[mitsumi]

Hi All,

Can you suggest anything that we can put to lessen the noise for both fenders.

There is a gap bet, and it makes noise while driving.

Don’t fill that void. Anything you fill that with will hold moisture and encourage corrosion in a place that will be difficult to reach.

If noise is the problem to be solved why not consider using something like dynamat?

I’m positive there is a piece of foam that fits in there on our cars. It runs up and down near the rear of the fender. I don’t know if my 2014 has it but I’m sure the 2015 and 2017’s I tore apart had them.

Basically where you circled in your second picture.

We have crazy wind here this morning. I didn’t notice any notice coming from there, just around the tops of the doors.

yes actually there was a foam but due to morethan 5 yrs of use of the car it already fell, but i mean it wouldnt be there if theres no purpose.

i would use

"Great Stuff Pond and Stone"

then i would paint the foam after it cured
but i'm a little crazy

(no idea how it would react to a car fire)
( and i would spray the area with silicone spray lube so the foam does not act like glue )

Ok so this morning i removed my mudflaps and checked the gap and found the foam was still inside so i put it back in place. I think this helps reduce the wind noise on the side.

and took the opportunity to clean the dust collected under the plastic cover for the wheel wells.

another one bites the dust!!
