I had a vintage VW that I was going to have a new interior put in and I purchased a bunch of sound deadener. I've since sold the car and am stuck with a bunch of expensive sound deadener.

It was one thing to think about them taking an old VW interior out and putting a new one back in. But on my 2007 Yukon XL that seems likely to cause some problems.

Has anyone ever had their interior taken out and put back in? I think I would benefit from the sound deadener. As I run all terrains. And I already bought the stuff. It was about $300-$500 worth of sound deadener. I haven't called the upholstery place to see how much it would cost to have it done. But it's certainly not anything I want to attempt myself. I'll leave it to the professionals. But only if I'm not opening a can of worms. If it's gonna result in a bunch of squeaks and rattles and things falling off. I'm not into it.

So anyone ever had this done professionally? Had sound deadener put in?

Never had it done professionally nor have done it myself. But, with owning 5 GM trucks over the years, I've certainly invested a lot of research into this. Some very recently, actually.

Whether or not you want to remove the interior is up to you and your comfort level with your skills. Once you remove a few interior panels of a GM vehicle, you pretty much learn how they're held in place and how to remove them without damage. Do the sound deadening correctly and you shouldn't create new squeaks and rattles, but eliminate them. In my Civic and in my S10, I had decent subwoofer setups that would rattle everything. I used an Autosound 2000 CD on my iPod to play bass frequencies from the low-20Hz range and increase it one Hz at a time. Different interior plastic panels would vibrate from different bass frequencies. I'd find and fix each rattle until I eliminated them as best as I could. It was very effective. I never did anything for damping the outside sound, just focused on tightening up the interior. You can get bags of GM interior panel clips cheap off eBay to have ready because some are bound to be broken, especially the door panel clips.

From my most recent readings, the floor and firewall areas are the biggest source of cabin noise, followed by that big ass roof area. I'd aim for the primary offending areas first and move to the others if I had enough material. In order, I'd focus on the floorboards and firewall, the doors (inner structure and outer skin, mirror "triangle", etc.), then the rear cargo area- particularly over the fenderwells. While you have the plastics apart, you can get a roll of adhesive-backed felt and apply pieces around the holes in the metal that the panel retaining clips snap in to. You may also want to apply thins trips of it to the edges of the plastic if it meets another panel (metal or plastic) and makes noise. This, and replacing the worn, brittle and broken retaining clips is what I did when chasing down the plastic rattles of my S10 and Civic.

To do the floor, it's best to remove the seats so you can remove the carpet. Now would be a good time to clean or replace the carpet. I wouldn't worry so much with sound deadening under the seats unless you have enough material. The seats themselves help to muffle noise so you can use that sound deadener elsewhere.

If you can afford to keep your Yukon off the road for a weekend and have the mechanical aptitude to perform your own brake job, then you can do this yourself. If you don't have the time or ability but can afford it- take it to a trusted shop.

Still undecided if this is something you should dive in to? There are threads here and on other forums with pictures and explanations for you to research to help you get a better idea of what's involved.

Ya. I've researched it extensively too. I wrote a huge thread/post about it over on the VW forum the Samba. I'm confident I know what needs to be done. I don't have the time or where with all to do it myself. If I do decide to do it I'll have a professional shop do it. It sounds like it's just about as straight forward as my VW. Just bigger and with a whole lot more interior stuff to think about. I just don't want things to go back in ill-fitted or loose. I guess I just have to take the gamble that my local shop will stand by their work. And fix anything that doesn't work or look right after the fact. They only wanted $1400 for an entire VW interior plus putting the sound deadening down for free. So I'm thinking it should run around $500 or so. I'm assuming. I just don't want to sell or throw away the materials I have. I'm probably close to $500 in materials alone. Can't remember the name of the foil backed stuff I bought. But is was pro level. And then I picked up some heat barrier too.

Thanks for all the insight. I think I'm going to put this on my list of things to have done.

As of today, I have installed sound deadener in my entire PPV. I did the floor when I replaced the vinyl with carpet a few months back. It helped alot with drone. This weekend I did the roof because I had to repair the rear ac vents. Should be alot better. I also put in some thinsulate on the headliner. Hopefully it'll help with this Texas heat .

How did your summer go? Any difference with the insulation?
