Howdy all, 1st time poster. First off I have reviewed many internet related problems similar to mine but can't seem to find a solution.

I have a 2004 Dodge Ram 3500 cummins, which I plow snow with. Recently when I would engage 4 wheel drive and apply power I would hear a clapping noise, does it in reverse as well. You can hear it best under 40 mph, but the faster I go the more drown out and consistent it gets. I took it into a mechanic and he inspected the front end and said everything was fine. It almost sounds like the transfer case, just speculation. I checked the fluid and its fine but has there been problems within the transfer case with this model? Any ideas?

 

I had a "sound" issue with my truck and it turned out to be my front universal joints. Was a clicking sound though not clapping

 

Welcome to the site but let me move this over to out CTD section for maybe more help.

 

Ditto here, but it only happens in 4wd. LOL, Mine sounds like a bunch of crickets under the hood. Hoping to get her into the shop soon.

Not to thread jack, but I get a loud clunk sound if I hit the brakes hard as well. Hope it's just from the front U-joints.

just went thru the same problem..while driving keep hearing a constant sound coming from some where (it sounded like the front end)..took a buddy a ride and he said it was coming from behind the rear seats....so we jacked up all 4 wheels and put it in gear...
TA DA we found it...it was the chain in the transfer case slapping around....for me while driving i could of sworn it was coming from the front end...funny how sound will throw you off trying to find it...lol
