Re: Rock Slide's 2002 Sport
I read how Bob_98SR5 did some sound deadening on his 4Runner and thought I'd give it a try. I have not put forth as much work as he has, but mine's a work in progress. For more information on his work, check out: http://www.4runners.org/articles/sound/index.html"]Sound Deadening[/URL]
It all started with a troublesome leak I had in the cabin of my 4Runner that I couldn't locate. Thanks to the advice of some members here, I found the leak and plugged it. Turns out, when I ran some additional wires through the firewall grommet, I accidentally pierced it. Every time it rained, water rolled off the hood, onto these wires and straight into my 4Runner causing the carpet insulation to mildew! I used some black silicone and sealed both sides of the grommet.
I removed the one-piece carpet and the thin factory padding that was glued to the carpet. Since I had half the truck torn apart, why not go ahead and lay down some sound deadening material and new padding.
My process in 3 steps:
Step 1 - The Cab
Step 2 - The Cargo area & Hatch
Step 3 - The Doors
For more information on the Sound Deadening material I used, visit: http://www.mcmaster.com/"]McCaster-Carr[/URL]. Part Number: 9640T2 in the 6" roll. It has a very strong adhesive on one side and an aluminum cover on the other. For the cab and cargo area, I used 4 and 1/2 rolls.
For the new padding, I picked up some 8lb carpet padding at my local Lowe's Home Improvment Store. They sell a 6ft wide by 9ft long piece for around $30.00. I lucked up and got the 9ft roll for $17.00 due to mispricing the item. I tried to find some for free, but no one was willing to let the 8lb stuff go!
Carpet padding is sold as 4lb, 6lb, 8lb and so on. When you need something above 10lb, the padding becomes heavier, stiffer and more expensive. It's also only offered as a rubber compound above 10lb I believe. 8lb is very firm, but molds very easy to many contours.
To secure the padding, I purchased 2 cans of 3M Adhesive Spray Glue #90 at Lowe's as well. This stuff's expensive, but well worth it.
I do not feel I need to further sound deaden my headliner, so for now I have only done Step 1 & 2 of my Three Step Process.
Step 1 - The Cab:
First was the cab. I removed all 4 seats, trim pieces and console pieces and then removed the one-piece carpet.
The sound deadening material is very easy to cut with a utility knife and molds to the floor contours very well. I applied it anywhere bare metal showed:
Next, I installed the padding everywhere I saw fit:
While the carpet was out, I went ahead and cleaned it. It was drying while I installed the padding:
Reinstalled all trim pieces and console pieces:
Put the seats back in and that's it! Step 1 is now complete!
Step 2 - The Cargo Area & Hatch:
I removed the roll bar, trim pieces and rolled the carpet back. I installed the sound deadening material all over. I then installed a layer of the new carpet padding down over the sound deadening material. The OEM padding was still in good shape on the fender carpet pieces, so I just reused those 2 pieces. You'll also notice I stuffed extra unused padding pieces into the empty spaces in the fenders between the sheet metal and trim pieces.
This picture shows the new sound deadening material layed and carpet padding over it:
Rear Hatch:
I've since reassembled everything and now Step 2 is complete!
To date, I have not done anything to the doors. I'm still trying to find time to finish the 3rd Step in this process. As time permits, I will post my progess.
As it stands now, the cabin and entire vehicle is much quiter while driving than it was before. This project was time consuming, but very worth while.

Re: Rock Slide's 2002 Sport
My 4Runner had fell victim to a severe case of undercarriage rust. Fortunately, it was only surface rust. Just a few weeks after purchase, I undercoated the entire truck with POR-15.
Now, for the "quick-n-easy" fix, check your local auto parts stores...Napa, Auto Zone, Advanced Auto or something similar. They stock many different varieties of undercoating in aerosol spray cans. If you do decide to use an aerosol undercoating, it might be a good idea to buy a few different varieties and test each one before you decide on a final selection. Some cans go on thicker than others. Some will also be in a brown colored undercoat, while others come in black. (I prefer black myself.) Do get something in a rubberized undercoating if you decide to go this route.
I've used both por-15 and aerosol cans as mentioned above on the underside of my 4Runner and truthfully, the aerosol cans are much easier to apply and touch up when needed. Por-15 is very labor intensive to apply and quite messy to say the least. If I had it all over to do again, I would without hesitation, go with an aerosol undercoating.
Google the following phrases:
1. Vehicle Undercoating
2. Rubberized Undercoating
3. Aerosol Undercoating
This will turn up even more ideas than what I have listed. Like I have heard good reviews about the 3M rubberized undercoating, so be sure to research that product.
Now if rust has completely eaten through some part of your truck underneath, then that is a different story...I cannot help you there. But if you simply want to keep the surface rust from spreading and/or forming, the ideas I've listed above will guide you along the way.
Can't seem to find any pics of my underneath from "before", but I did find this one picture after I had finished:
