Hey Gang. This is my first post and I'm looking for some help. I have an 06' 1/2 ton with the Hemi, quad cab, and 20" wheels. I'm getting a vibration for a few seconds when I let off the throttle. It happens at about 30-35 mph and 1000-1200 rpm's. The dealership gave me some BS story and said it is the cylinders cutting back and is normal. I'm gonna call Dodgeon this and was wondering if anyone else has had this problem.
Thanks

 

cylinders cutting back. . .now thats origional[>:]

sounds more like theres an issue with the torque converter not unlocking fully or an issue with some of the solinoids in the tranny.

 

Similar deal here. A new '07 that vibrates around 60. Thought it may be the tires but the dealer jumped on it declared an out-of-balance driveline. Waiting for the new to come in so we'll see.
