Can't be dual exhaust since I have the same prob on ST quad without dual.

 

I have read all the pages and i am having the same problems but to me it feels more like a clunk than a vibration. Like many people here i have taken it to the dealer but to no suprise the have yet find the problem. I have put Dynamat on the bracket that the pedal is bolted to but it didn't work so what i am thinking is its the pedal itself. Has anyone tried replacing the pedal to see if thats the problem.

Oh and i have a 09 Ram 1500 SLT Lone Star Edition 2WD CCRB.

 

its not the pedal, its a harmonic vibration. That is if its the same one im feeling. Something is out of balance, i really notice it travelling at or through 30km/hour, at any throttle setting and even when you are off the gas and coasting it is noticeable. It goes through the whole truck, but since im driving I feel it in the steering wheel and in the gas pedal.

 

if its a harmonic balance issue, why wasn't it felt right off the bat. Cause when i got it brand new i had no issues. to me it seems more than just a harmonic balance issue.

 

I have said since the start of the post that it appears to be a harmonic problem at certain RPMs. The good news is that as my engine has loosened up a bit with 16K miles, the buzz has decreased a good amount. It is still there, but the rpm band that causes it has narrowed and the buzz is less severe. Mine did have it from day one, big time.

 

I've had it since day 1. You probably did too, just didn't notice it? Mine has also become slightly more tolerable. I didn't notice it on the test drive but a day later I picked up on it because I was getting used to the truck

 

I noticed mine on the first day I had it (yesterday). Just thought I'd check here before calling the dealer to see if was a known issue. Looks like there isn't much point in trying to get it fixed. I feel like it happens only when the MDS is engaged, although I only have put about 100 miles on it. Hopefully the thread will stay alive until someone figures it out. Something that I have noticed on mine that I haven't heard mentioned here is that besides feeling the vibration in the gas pedal, I can actually hear a vibration coming from somewhere under the dash. Possibly some plastic vibrating.

09 Hemi CC Big Horn, 3.21, fixed pedals, built 4-9-09

 

Put a couple of hundred miles on it over the long weekend. Definitely feel it with and without MDS engaged. It does change depenting on pavement. Rough pavement has worse vibration than smooth. The vibration noise from under my dash has stopped, but it can still be felt in the gas pedal. Do all of these trucks with the vibration issues have the same tires from the factory?

 

I have different tires, there's still a vibration

 

OK I have got one for you.....

Finally got my Chrome clad 20's on there replacing my 20 inch Alluminum non chrome, and now it has a Resonance vibration, almost like the chrome clads are vibrating, there is a RRT for this on other years and I am going to get it and post it, its worth a try, I love these wheels but not enough to like the buzzing feeling on the pedal, IT NEVER DID THIS WITH MY ALL ALLUMINUM WHEELS, the fix on the RRTwas to put RTV in the gaps where the chrome clad just hovers near the edge of the wheels, you can make the wheels make a sound by pulling your finger across the edge where there is NO epoxy....
