hemsteadc Posted November 13, 2014 Report Share Posted November 13, 2014 I'm having wind noise issues in the cab of my 2008FL M2 Sportchassis. Sounds like it's coming from the window/door frame along the top and front edge - but it's hard to be sure. Anyone try to solve this using any kind of wind deflector?

GeorgiaHybrid Posted November 13, 2014 Report Share Posted November 13, 2014 Have you checked the door fit and the gasket between the door and frame? 2017 Kenworth T6802015 DRV 38RSSA Elite Suites2016 Smart Prime Link to comment Share on other sites More sharing options...
rdickinson Posted November 25, 2014 Report Share Posted November 25, 2014 There was a lot of noise in my old 4700. The mirrors were the old style metal attached to the door. My understanding was to use a different style mirror attached to the cab. Link to comment Share on other sites More sharing options...
skp51443 Posted November 25, 2014 Report Share Posted November 25, 2014 On my IH the wind on the mirrors was prying the gap open and letting in a lot of noise. Re-adjusting the door hinges to move the top corner in 1/8" was enough to stop the noise. You can test this by pressing on your door at the top corner at just below the speed it makes noise at to see if it starts.

jblscooper Posted November 25, 2014 Report Share Posted November 25, 2014 Not sure about the M2, but had the problem with our '96 FL60. Foam pipe insulation, about 18" long, split down the middle and pressed into the gap between the edge of the windshield and the trim corrected the noise to a manageable degree.

hemsteadc Posted December 2, 2014 Author Report Share Posted December 2, 2014 Thanks all. After much inspection of the area, I find there's no actual leakage, but just noise. As you may know, this model has wing windows, which the Sportchassis shop mentioned as one of the possible causes. That, and those big side mirrors. I was thinking that I could use a bar, vertical, clamped to the top and bottom horizontal frame rails of the mirrors, and then attach to it some sort of wind-deflecting vane like a piece of aluminum. Then go out and drive around and see if merely deflecting the wind would help. That, or get painter's tape and block off areas until I find it.

porky69 Posted December 2, 2014 Report Share Posted December 2, 2014 I like your thought of trying painters tape to cover things up until you find the source. I would start by covering up/filling the gap between the door opening and the door itself. Link to comment Share on other sites More sharing options...
hemsteadc Posted December 3, 2014 Author Report Share Posted December 3, 2014 I would start by covering up/filling the gap between the door opening and the door itself. The door seems to fit just fine. My absolute first task will be to thoroughly clean the rubber around the door frame. I had wanted to stop by Sportchassis in OK a few weeks ago, but the weather turned horribly cold. I was told there would be silicone involved, which needs 24hr to cure. I didn't assume below-freezing temperatures were going to be conducive to that. Link to comment Share on other sites More sharing options...
beetlebob Posted January 1, 2015 Report Share Posted January 1, 2015 I moved the support arms forward one click on pass side and 2 or 3 clicks on drivers and repositioned my mirrors. Quiet. Without a picture I do not know what mirrors you have on yours. Mine are factory since I had my truck custom built by Freightliner. Link to comment Share on other sites More sharing options...
hemsteadc Posted January 10, 2015 Author Report Share Posted January 10, 2015 I've tried bending the door frame a couple times. Seems to help. Link to comment Share on other sites More sharing options...
