I recently purchased a 2003 F150 and already drove it all day to Oklahoma and back. I decided I would make an effort to quiet the cabin. Although I'm pleased with the lack of wind noise, I thought I could do better. I know some folks like a rumble to the exhaust, or a cranking stereo - don't get me wrong, I like to jam too, but sometimes I don't want to hear much outside of the truck.
So I removed all four door panels (Supercrew). I glued another 1/2 inch layer of felt insulation (purchased at an interior supply shop) over the existing door panel insulation - this is attached to the back side of the panels. But I also put a layer in the other areas of the panel where there wasn't insulation.
I pulled off the door sill trim (rubber too) and cramed insulation along the door sills - word of caution - if you're a guy who gets your truck in the water above the door sills, don't do this because the insulation will hold water creating rust.
I pulled back the B and C post plastic trim the best I could and crammed more insulationg in there, careful not to overstuff causing the trim to stick out or foul the seat belt pulley mechanism.
This addition of insulation greatly reduced the noise and rattles in the truck. I guess some of the panels had rattles.
The next step is to add a layer of insulation under all the carpet and behind the rear seat.

Has anyone experimented with injecting expandable foam sealant into the thickness of the doors and other areas?

If you do a search on sound deadening on the board, you should be able to find many threads on this very topic. Most people do it to upgrade their sound system but it serves the same purpose as what you are doing. Also there are better materials for doing this that are specifically designed to reduce the noise without holding in water and will probably do a much better job on the noise than what you are using.

 

I wouldn't, where's the window going to go when you put it down?

Anyway, they make some stuff called second skin...this guy installed it in his Ranger, said it worked well...

Those sound like good improvements but keep in mind it'd not a Lexus.

 

I recently put a pretty awesome sound system in my truck, I took the whole interior out and used fiberglass insulation to fill in the the cab ( just pulled it apart off the roll) , its a 3 door supercab so I packed it in the 3rd door on the passenger side , the back wall , the part that would be the 4th door , put down jute padding on the floor completely it's about a 1/2 inch thick and i put it on the rear wall... Put down a new Nifty carpet kit and you can hear the difference... Less road noise for sure and no hollow rattles..

 

I believe that's exactly what Ford did on the '04 redesign.. well, not in the doors, like deapee says those windows gotta roll, but inside of all of the cab framing.. the 04+ cabs are the quietest pu cabs I've ever been in..

 

you might want to look into dynamat...i have it in my truck and it works good...hope that helps...

 

I helped Jwool15 out of Ft worth sound insulate his 05 truck.... We used "Great stuff" expanding foam between the two layers of the back wall and pilars.... Then layed Edead's version of dynamat down on the back wall and floor. He later did the doors b.c we ran out of time. But its a great way to make a truck even quieter... The Edead is kinda pricey, but its still cheaper then paying for the name dynamat.

I just used some cheap foam insulation on my 03. and i was pleased with the results at the time (for 100$ it did the job) but id like to go back and use more permanant stuff on the back wall and floor. I like having the foam in the doors b.c i can easily remove if when im installing the cross overs for my speakers, or eventually im sure ill need to change out a window motor...

If youve got any questions, or maybe would like some help on a weekend email me and we can talk numbers
