I drive a 08 charger 5.7 Work Vehicle. The vehicle has a vibration in it. I started driving the vehicle with around 80,000 miles it has 104K on it now. Really did not notice the vibration when I sarted driving it. It has gotten worse over the last year. During normal driving around 20-40 mph in overdrive it has a vibration. If you take out of OD it seems to smooth out some. During Intersate driving it seems to vibrate more the faster you drive. shifting out of OD seems to help. Tires,Good year state issue, rims, factory, have been checked and rotated. The rear end has been removed. new bearings and bushings have been installed. New motor mounts have been installed passenger side was found to be broken. Has someone else had a simuliar problem. Just took back to the shop. Dealership stated the drive shaft was ok. Could it be in the tranny? That is the only thing that has not been replaced. Any ideas?

 

The Mechanic stated he felt that the drive shaft had a little more play in it than it should have. A new unit has been ordered. Will see if this helps.

 

what fixed this? Can you give us an update?
