I have a 2007 Ram 1500 Quad cab w/Hemi. It has the 20in wheels.
Between 40-60mph there is a slight vibration around 1700-1800 rpms. If you gas it a little it smooth's out, if you turn off the overdrive it goes away also. It is annoying because when you are attempting to maintain a cruising speed, you are at those rpms, so it is vibrating quite a bit of the time. I know it rides a little rough because of the big tires, but this is something different.
The service department said they were aware of this condition, and said it was normal.
is it really normal?

I am having the same deal with a shudder. So far I have had the rearend rebuilt, I have a new drive shaft, a new torque converter, a new valve body and over three weeks in the repair shop.. So far the vibration has thwarted all of their efforts to eliminate it. I was told that the technical service at chrysler are aware of this and that there is a tsb coming soon, right now it is "code black" whatever the hell that means!

I have a 2007 hemi sport, I am experiencing the same problems that you are having. My dad and i have bought 5 new dodges in the last three years and this has been the first bad issue. The dealer keeps making things up like the tires are not mounted proper,Bad roads and the list keeps going, One would think that if you pay $38,000 for a truck they would try and make you happy.

I own a 2008 Hemi 5.7 Grand Cherokee that experienced shuddering around 40 mph. It calls for 89 octane. I increased the octane and it got worse. I went down to 87 octane and to my surprise the shudder went away. I contacted the dealer and told him about this find. Lower octane gas burns faster where higher octane has a longer burn off time. Higher octane will burn from the center of the piston outward similar to dropping a pebble into the water and watching the ripple affect. Give it a shot and see if it works for you.
