Did anyone ever find out what that vibration is from? I have a 06 2500 Hemi and get a 1 second vibration at 1200RPM. I have been underneath and can't find a darn thing. I am waiting for a day off from work to take it in. I have sent emails to Dodge and various dealerships but have not heard anything in return. Let me know if anyone finds out what it is. Thanks.

 

From the Dodge website... "The advanced Multiple Displacement System (MDS) uses electronics to switch from eight cylinders to four during cruising and light acceleration..."

I can feel it switch over, and it not just a downshift. I find this system quite annoying, and for the extra 1mpg, I dont think it's worth it. Just my .02

 

I don't have MDS on my truck. Still waiting for a day off to take my truck to the dealer to find out what that damn vibration is.

 

I had a vibration real bad at 25 then again at 55 for about a week and this is what happened.

If it starts getting worse take it in.

 

Anyone else have the driveshaft problem?

I have a vibration that I thought was a Goodyear problem. I have went to the dealer and to Goodyear with no results... Tires are in spec.[:'(]

Thanks,

I just got mine today and I have a very slight vibe at 60 mph. Any speed higher or lower...no vibes. I only have 80 miles on it now so I'll give it a bit before I take her back in.

 

I got a new ram truck about 2 months ago, I have this vibration, did anyone ever find out what it was? Ive taken it in 3 times and dodge has no clue.

 

ok dude seriously, there is no possible way you can feel the MDS kicking in. you're imagining it in your head or something. if you had any idea of how the MDS worked and read about it you would know that you cant feel it kick in. seriously, get the hell off what ever the hell your smoking and learn bout it before you critize the operation of it.
