I'm going to apply bed liner under the carpet in my Cherokee, will this kill any of the road noise, had anyone done this?

 

I doubt it. Try something like this

It will help, but probably not enough to notice.

Dynamat will work as suggested.

 

X2 Exactly what gee said.

 

My floor is bed lined but no carpet put back in I can tell you that with out the carpet it does next to nothing to deaden sound, I can hear every bushing every tick , jingle , so on and so forth

 

Try this it works well, I've used in my 74 Nova SS.

Peel-n-Seal which is cheap and can be purchased at Lowes is a good poor man's Dynamat

 

Nice thanks for this I will have to try this out. Looks like you can get a roll of the stuff for just $16.

 

Found this while checking "peel-n-seal" out:

"Just to let you guys know that peal and seal is actually Ice and water self adhered underlayment people in the roofing business (like myself) use. Works really well on low sloped roofs.
As a reference for installation, everyone should know this should only be applied typically when the surface is 40 degrees or higher (knowing that most of us are having cold temperatures).

Just a fair warning. I've been around this stuff quite a bit. Being that its cold right now you might not notice it but when the weather warms up and the cars starts baking in the 80+ temperatures you might start to get a freshly paved asphalt smell or almost tar-ish smell in your car. That will be the ice and water underlayment baking. We sometimes have it in our office and its stinks up the whole d*mn place. Gives you a headache after a while. Just wanted to let you know. It will take a long long time for the smell to go away.

As a reference here is a volvo forum where people used the same stuff and were talking about the smell."

Yeah I read that too. But I also read a lot of people saying that they can't really smell it. Plus my jeep already smells chemically since I redid my headliner haha.

 

Driving with a buzz?!?! LOL

I was actually checking out the p-n-s as a replacement for my sagging headliner.

 

After you apply the Peel-n-Seal to the floor, you should cover the floor with a layer of plastic sheeting using duct tape to hold it in place. This acts as a vapor barrier. I have a thread somewhere called My Daughter's XJ which has some photos. I never smell anything, except myself on occasion.

Stuff the rear wells with insulation for additional sound proffing. It works.
