Air Noise!!

[cajunjohn]

Hi Guys!

Anyone have a whooshing sound (air leaking) from the front corners of your coach at about 45 mph and higher?

All outside areas (winshield and windows) appear to be well sealed, with the exception of the drain holes of the windows.

Any ideas as to what to do, except for using walkie talkies?

Thanks in advance, guys!

Do a search on this forum. It has been discussed before. (Probably 2007 or before)

The problem is with the sealing of the front cap, IIRC the air is traveling up the side pillar(s) from the outside of the firewall. Some spray foam will seal it off.

Here's the thread I found with my first search (see post #8).

Entrance door wind noise

There are a couple other threads discussing ways to temporarily isolate the source (using tape). It seems noise at the front end can be the cap or the door.

Try taping over the weep holes on the windows with black electrical tape and see if that noise gets quieter. Remove the tape when washing the coach or in rainy weather.

Try f0am rubber door and window seals. Comes in a roll 1/2 in wide with a self adhesive back. Run a strip up each side of the coach between the gen slide and coach body. Clean surface first. This cheap fix cured all front end wind noise. Also use it around the front door. Be sure to use the foam material and not the darker harder rubber stuff. Slide will be able to close completly and foam rubber will fill all gaps. Cheap too. Found at Lowes or Home Depot.

To check the side pillar air leaks, take about 10 plastic grocery bags stuffed into one, smash it up tight & insert it into the pillar void(s). Then drive to see if that helped.

TakePride, you are the MASTER! The foam sprayed into the area under the roof pillar worked like a CHARM! I am indebted to you for my sanity!
Sincerely,

O. K. here we go again to show what little I know. What and where is the pillar ??

[Jeff and Cheryl]

Dave,
The pillar is the (for lack of a better word) pillar that seperates the windshield from the door opening.

[Old Rv'er]

This must be indigenous to a front entry only, we don't have this noise as we have a mid door.

[cajunjohn]

The pillar is actually the vertical member which 'supports' the roof. It is located on both sides of the windshield, between the windshield and the side windows.

To access the area to spray insulating foam, open the front hydraulic slide, go into the space created, and look up into the outside corners as far up as you can see. You'll likely see some old foam sprayed into the uppermost corners that you can see, which corresponds to the underside access to the roof pillars. Generously spray the insulating foam into these uppermost corners, let it cure, and take a noise-free drive!

Let me know how it works!

Thanks Cajun John. Can I reach up in there far enough to use a spray can of foam that can be purchased from Lowe's / Home depot, etc. ?? Or do I need a special set or something ? Dave

[cajunjohn]

I got mine at Lowe's. It is plain household insulating foam. Worked for me like a charm. Let me know!'

There is a black foam, sold at auto parts stores, too. Not sure, but I think it holds up to the heat better than the foam-in-a-can I use around the house. Seems more rubbery. It might be more flexible. You should check the flammability difference, too.

The black just seems to look better, too.
