pflaming Posted March 27, 2013 Report Share Posted March 27, 2013 My truck runs great, but the road noise is deafing. Maybe what I used for insulation has little effect. How much noise do door seals keep out? The noise is NOT coming from below but from all around,so I gather it is largely windflow. Some pics of our drive to the Giant Sequoia trees today, a 6,000 foot climb in 30 miles, a good test for an old vehical. We went all the way in 3rd at a speed around 45/60 mph.

TrOjAnUK Posted March 27, 2013 Report Share Posted March 27, 2013 I must agree.. went on a run in mine and the wind noise is high.. I have replaced the door seals and think I might have stopped about a foot too short. My noise is from the top of the door where I did not put any rubber.. Ill be adding some more soon so hopefully will cure it. Hope you get it sorted, TrOjAn Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted March 27, 2013 Report Share Posted March 27, 2013 I find that it is quieter with the window down and the vent window angled open a bit. Apparently it changes the air flow past the door enough to quiet it down. Merle Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted March 27, 2013 Report Share Posted March 27, 2013 A lot of the noise you hear comes from the radiator cooling fan. Quote Link to comment Share on other sites More sharing options...
pflaming Posted March 27, 2013 Author Report Share Posted March 27, 2013 60% of the return trip from the mountains is coasting, yet the noise is there. I do want to replace the cooling fan. Is there a six volt fan available? I am ordering door rubber from Steele today. Got to quiet this down for the trip to the BBQ. That will be a three hour drive.

ggdad1951 Posted March 27, 2013 Report Share Posted March 27, 2013 FEF is loud as well, these trucks weren't designed to be quiet as they are nowdays. The proper sealing around the doors should help deaden some of it, but I CAN have a conversation in FEF while BLAZIN down the road at 47mph....just have to be a bit louder than "normal".

Don Coatney Posted March 27, 2013 Report Share Posted March 27, 2013 Your cooling fan makes as much noise while coasting at 50 MPH in gear as it does when going up hill at 50 MPH. Engine RPM's are the same unless your clutch is slipping. Quote Link to comment Share on other sites More sharing options...
pflaming Posted March 27, 2013 Author Report Share Posted March 27, 2013 (edited) Don, thank you, your post reminded me that the engine's rpms do not determine mph, the tranny does that, so coasting the engine while not pulling is still turning the rpms. Got to find a fan for a six volt, since I'm very hearing challenged, only one ear left, I want to get it as quiet as possible. I'm still amazed at how easy this truck steers, Don you got to get a truck in order to experience the ULTIMATE MOPAR HIGH! On the way down the mountain, we pulled off to take a picture by a 49 bullet Studebaker parked as yard art. The owner saw the truck and called for us to wait up. First, he is an artist so he swooned over the patina, then he took us to his yard where he has four complete studebaker cars. This station wagon is the pick of the four. Probably a bit rare. I got to learn how to make my picture posts smaller. Edited March 27, 2013 by pflaming Quote Link to comment Share on other sites More sharing options...
Jeff Balazs Posted March 27, 2013 Report Share Posted March 27, 2013 I am curious. How much of the noise do you suppose comes from the area around the drip rail versus the door sealing arrangement? Quieting things down can be one of those items that I figure make the difference between a decent build and true success. I know that I am planning on spending a fair amount of time to sort this out on my truck. I wonder if anyone here has come across some of those metal aftermarket wind deflectors that were popular back in the day? I think they were polished aluminum and went around the upper section of the windows. Not the universal type but the ones that were made to fit specific models. Seems to me a good fitting set of these could help with the noise? Jeff Quote Link to comment Share on other sites More sharing options...
Scruffy49 Posted March 27, 2013 Report Share Posted March 27, 2013 You could try a more modern clutch type mechnical fan. I test fit one just because I had a spare laying around. It fits the mount on the water pump fine and fit the truck before I took the front end apart. Came off a 4 cylinder Ford. Peel and stick foam tape under the floor board panel seams also helps. Transmission cover plate, battery cover plate, removable toe board... Helps cut heat, dust, fumes and wind noise. And believe it or not, the 3 piece hood adds a lot of sound to the equation. The center seams over the hinges can whistle, roar, rattle, clank... Add some extra sound deadener under the seat. Maybe put plates over the access holes for the fuel tank. Anywhere air can get to is going to make some form of sound in the cab. Quote Link to comment Share on other sites More sharing options...
lugnut123 Posted March 27, 2013 Report Share Posted March 27, 2013 In my daughters b-1-B we installed aluminum foil insulation insude the doors, in the kick panels . Any where inside the cab we could put it. Even under the floor mats. That old truck you cann't even hear the muffler anymore. Noel Quote Link to comment Share on other sites More sharing options...
Young Ed Posted March 27, 2013 Report Share Posted March 27, 2013 Paul what do you have for an interior so far? What type of firewall pad, headliner, floor covering, kickpanels, door panels do you have so far? My truck is fairly loud but I typically have the windows and windshield cranked open so there's plenty of wind. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted March 27, 2013 Report Share Posted March 27, 2013 wind would be you first guess as your ear is closest to the door sealing area when driving...as others said, insulation and sound deadening material in the doors, overhead, behind the cab and floor/firewall will go a long way quieting the beast..do not expect to achieve the sound level of the modern vehicle with aircraft style doors..are your vent seal in good shape also..they usually provide a whistle effect..when installing door seals start at the top center with the material so as to meat in the middle of the door's bottom for best sound and water proofing..

If I'm reading you correctly, I'd disagree, The seal on the door itself starts a liitle past the bend down for the wing window and the cab seal starts fowrard of that. There is about 4" of overlap between the two seals. door seal: Cab seal: Edited March 27, 2013 by ggdad1951 Quote Link to comment Share on other sites More sharing options...
pflaming Posted March 27, 2013 Author Report Share Posted March 27, 2013 I rechecked my door seals. The passenger door seals are GONE and the Driver's door are hard and broken. I just ordered a set from Steel Rubber. That will make ahuge difference. I have a rubber based sound dadener in the cab, it was free and probably does about that muhc good. Thanks for hte tips. 1 Quote Link to comment Share on other sites More sharing options...

Merle Coggins Posted March 27, 2013 Report Share Posted March 27, 2013 Paul, These little seals work wonders too. I will admit that before I put in my Quiet Rides interior, the cab was quite noisy. Afterwards it was remarkably quieter. I also installed a better muffler to quiet things down some, but the interior stuff did most of it.

JBNeal Posted March 28, 2013 Report Share Posted March 28, 2013 Get your truck up to cruising speed, then cut the motor off and push in the clutch: thar's yer wind noise My '48 has practically no noise insulation: the original firewall pad is almost gone, the original door seals are history, the headliner...heck I've never seen it. When sitting in the driveway, with the doors closed & windows rolled up & engine off, the open glove box door slamming shut actually makes an echo. So the bare metal cab acts like an echo chamber. I have a new floormat with the padding and tried it out once...it made a heap of a difference. It didn't make it Imperial quiet, but my ears weren't ringing as bad after I rode into town. Looking at my '02 CTD, it has a perimeter door seal, and then another door seal from the bottom of the windshield to the back of the cab, the doors have plastic door panels from the window sill to the door sill, carpet with padding from the padded firewall to the carpeted cab back panel, and a full headliner. That oil burner (almost twice the size of the flathead) makes plenty of noise, and all of this insulation helps but it's still a loud ride (ears ring a bit on trips longer than 1/2 hour). When I drove around for a couple of days with the rear window busted out and the rear liner removed, that truck was LOUD. So if ya want a quiet ride, ya gotta button up every surface leading into the cab. Quote Link to comment Share on other sites More sharing options...
HanksB3B Posted March 28, 2013 Report Share Posted March 28, 2013 I'm using a six blade fan. Slick told me to use it instead of the 4 blade. Don't remember why maybe he said it was quieter? Not in the Know, Hank Quote Link to comment Share on other sites More sharing options...
Dan Babb Posted March 28, 2013 Report Share Posted March 28, 2013 Sound deadener does wonders. I put it on the floor, under the seat and along the back wall (up to the seat back so you can't see it) and the noise is greatly reduced. Won't stop wind noise, but you'll be surprised at what a few rolls of Peel & Seal from HomeDepot or Lowes will do to eliminate noise.
