Hi,

1st time here.
I have a 05 ram 2500 4x4 diesel
Just put my truck into 4 wheel drive, during snow and while just wet road conditions.
I'm getting vibrations only during acceleration and at speeds greater than 20 mph. When I shift back into 2wd the vibration stops.
Thanks.

 

How bad of a vibration? You will get a different "feeling" when in 4X4. If you are concerned, have a look at the CV joints and front drive shaft U-joints.

 

Thanks for the reply...
I have NEW U Joints and I've been driving all winter with no problems.
The vibration is similar to driving on a gravel road. I'm thinking its a HUB issue...possibly only one engaging.
It's not noticeable at slower than 20 mph

 

Oh...but I have not changed the DRIVESHAFT U Joints

 

Maybe a bad u joint in the front drive shaft. IMO I would do them all.
