After having my rear drive shaft replaced, the vibration in 2WD was gone. We got a bunch of snow the other day and after shifting into 4 Lock, I noticed another vibration. I dropped it off at the dealer and they did acknowledge the vibration. They then took another two new trucks off the lot and test drove them in 4 Lock and got the same vibration. They then checked some sort of internal dodge dealer web site and this problem has now been reported enough times that it is becoming a service bulletin that at this point has no fix. So all you 06 4X4 owners, next time you are out, switch into 4 Lock and accelerate hard and report back if you are getting the same vibration, I am interested..

Thanks

 

New suspension and frame, end result, bugs. This is why it is never good to buy a car in year one, although it looks about the same the underside is very different.

 

What TSB number did they state. I have looked in 2005 and 2006 and dont see it?

 

I dont know if there is a number yet.. They said that they found numerous similar complaints on some internal web site. Do you have access to the site they are talking about?
