Anyone been able to sound proof-ish a series?

[LR Max]

One of my goals for this year is to sound proof the 109. I hate to sound like an old man, but comfort is becoming a bigger requirement for me (I re-sealed the doors and they fully seal now, re-did the seats, few other little bits).

Sound proofing is something I'd like to add to the 109. Currently my plan is to strip the interior and dash and paint the entire interior with lizard skin heat and sound proofing. Also pull the top and install sound proof matting and a headliner (just to keep sound from echoing inside).

Considering doubling up with dynamat on the bulkhead, floorboards, and seatbox. Also might look at getting one of those molded interiors. Only issue is my truck is an ex-mod so I have to pull the seats to get to the gas tanks.

As you can see, I'm threatening to seriously try and quiet this stupid truck down. I think it would significantly reduce fatigue when I'm in the saddle all day and make simple around town jaunts simple instead of giant productions.

Thanks for any help!

I have, and had pretty good results, but I used a list of products that are probably not available over there: WrightOffRoad matting in the cab and the tub, Noise Killer mats on the hard top sides (you will probably find a similar product in the US), a LaSalle head lining with camping roll mat behind it to prevent drumming and aid insulation, and Defender doors to reduce drumming and echoes but also to reduce draughts and airflow noise. Still, my work might give you some ideas. Have a look through the "interior" section on my blog.

Dynamat on the door skins makes a remarkable difference. No reason to double up with the stuff anywhere, because it does not really absorb any sound it just keeps panels from resonating. Even a small amount of Dynamat strategically placed is very effective.

Not sure how you re-sealed your doors, but the best way is to use Defender 1 piece door seals. They install easily.

I've never seriously tried, but have looked at the molded matting kits.
JC Whitney used to sell a heat reflective and sound proofing matting that you would attach to the bulkhead in the engine compartment. Lot of work there of course.
As for accessing your fuel tanks you could always add civilian filler necks. The tube on the tank is just soldered in, so it would be easy to add one.
The outside filler neck will fit either side and you'd just have to fashion the hose for the left side filler.
Another option would be a 12v fuel transfer pump so you only have to fill the right tank at the service station. You can get high GPM ones fairly cheap.

I did a lot of work on soundproofing my Defender 110. A headliner was absolutely the best improvement.

Post 37 is the start of the headliner stuff. There is some info about what I did for sound deadening in the doors and dash earlier in the thread: http://www.expeditionportal.com/for...ender-110-build-up-for-South-American-travels

Thanks for all of the input!

As others have suggested, I have gone with Defender door seals and defender vent seals. So much better than the series seals that were on there.

ExploringNH, I will read your thread. Thank you for the input. I guess for right now, insulating the roof (maybe add a sunroof...one big enough for me to stand out of so I can look around in traffic with binoculars and freak out others!) and the doors would be a good place to start.

Thanks again!

(maybe add a sunroof...one big enough for me to stand out of so I can look around in traffic with binoculars and freak out others!)

LOL too funny. I keep binoculars with me and sometimes when I'm looking for a place down the road I'll pull them out while at a red light to see if I find a sign. My wife always laughs and says something like, "Tom, put your perv binoculars away!. I don't want people seeing me with you."

I have had a lot of luck sound proofing my Defender with a roofing product called Peel N Seel. It is similar to Dynamat. I bought 99 sq ft. roll at a local hardware store for less than $100 and lined my entire truck cab with it and had tons to spare. Just cut to desired shape and stick it on. It is an asphalt impregnated material and is pretty heavy duty. Nay sayers told me I would have a petroleum smell after installing it but that has never been the case. I have spent weeks in 100 plus degree heat with absolutely no smell or off gassing. I lined my bulkhead, roof under the headliner, that was a huge help with noise, doors, tranmission tunnel cover hood, seat boxes etc...... It worked great for me. The only warning is do not place over nuts, bolts screws that you may need to get to in the future because it's a pain to take off once it's on.

^WOW thanks! I might just give that a shot!

Also guess I need to start looking at actually having an interior to cover it up. Such is life.

Thanks again!

another name for that roofing product is ice gaurd it is the same as dynam matt it is made in the same factory. just one is foil coated and the ice gaurd is a white plastic. Just make sure you put it down on a hot day so you get full bond and it does not hurt to use a red scotch brite pad first to get the paint shine off.

paint shine off

Have no fear. "Shiny" isn't one of the words used to describe my 109 :elkgrin: . But yeah, probably a good idea to rough up the paint just like putting down a coat of primer. Also grease free.

It isn't warm right now, but I might try using one of those cheap northern tool heat guns. That might help along with some 3M adhesive spray.

Thanks again for all of the information! I'm excited now to get this done!

We have had great luck with dynamat extreme (or knockoffs) combined with raptor coating and rubber matting. No one thing will really make it quiet but the combo seems to work very well.

Here is a link to a 109 we just finished with full (almost) soundproofing. Most of the soundproofing related are in the middle

Thanks. My current plan is to spray down the lizard skin coating (both sound and heat proofing) paint-stuff. Then cover with probably one of those dynamat knock offs or dynamat equivalent (or maybe dynamat if I can actually find it for a good price!).

Only issue I have now is trying to find a "finish" for the inside of the vehicle, unless I can figure out how to make the dynamat application look fancy.

Also seriously considering doing a full cosmetic re-do on the 109. The body is all beat to crap and a fresh coat of paint would look spiffy. I remember seeing a youtube of some guys doing a roller paint job. But then they sprayed it over with custom paint in a spray can. Then I thought, why don't I just get a box of custom spray paint made up and do the entire truck like that!! Would be nice to have the old girl looking like a show truck again.

Anyway, thanks for all of the input!

Call badger coachworks and order a carpet set, they will make everything to your spec including new hardura panels for the footwells/etc.

I realize it's a little on the primitive side....but I just stick those little foam bits in my ears.

They're cheap, portable, don't contribute to any corrosion forming condensation, and certainly don't remove any paint
