Wheel well sound isolation - E450

[jabrabu]

I have a Chateau class C. I added insulation to the doghouse, which helped reduce engine noise somewhat, but there is a lot of road noise from the front tires and/or hubs. Any suggestions on how to insulate the front inner fenders? Has anyone here done this with good results?


I doubt that thin plastic inner fender liners would do a lot. How about rubberized spray-on undercoating? Maybe Dynamat -- where exactly would you apply it?

There's install info and part numbers for wheel wells that fit an E450 in my signature thread.

Where is the link? I don't see one.

Are the parts from amazon

How do I find your signature thread?

[jabrabu]

The link is in ducksface signature in his post. However, it doesn't take you directly to the info about wheel well insulation. I did some searches in that thread and found some info about wheel well liners. His RV is an Axis class A and mine is a class C, so I'm not sure if the inner fenders are the same. It looks like the liners he used are made for a Dodge.


If search for E450 wheel well liners, you can find some, but they look like they are a thin piece of plastic that partially covers the inner fender, so I don't think they'd do a lot for noise isolation.

My browser definitely doesn't show any signatures or links after duckface's post. If you see it, how about paying a link.

I looked online for e450 wheel well liners and haven't found anything.

I think this would probably fit. It says through 2014, but I don't think the Econoline has changed since then, it just became unavailable as a van.

Google Noico on Amazon. Sound deadening adhesive mats & cheaper than Dynamat.

I have used about 30 SQ ft of the noice mat. I used it to quiet rattles in the cabinets and under the dinette from a subwoofer that I added. It works great. Definitely a great value.

I used kilzmat on the entire floor inside the cab. Then rubberized undercoating in the wheel wells. Can actually hear the radio now.

Thanks everyone.

I have added insulation to the doghouse, which helped engine noise somewhat. I also noticed that there is a horizontal sheet metal piece between the engine and the dash, and I think adding a layer of insulation to that might also help.


I bought a pack of the Noico a while back, and I'm planning to insulate the floorboards and firewall inside the cab, but I haven't gotten to this project yet.


I just replaced my front tires and got another alignment done, and the road noise has significantly reduced, so a lot of it was tire noise. Now I'm noticing more wind noise.


There is a plastic fender liner inside the wheel wells, but it is thin plastic and only covers the outer 6 to 8 inches, so it's not doing anything to reduce noise. The combination of adding sound deadening mat on the cab side and some rubberized undercoating on the underside should help a lot. I'll add it to my list of projects.

Anyone know where I can find wheel well liner for axis E450
