Ok, this is not good. I bought my truck in march and I mentioned this situation somewhere on this site awhile back. Shortly after I had my truck, we had a very wet snow about 8". I drove to work that day and when I came out to go home as I got to about 40mph, a bag I had on the passenger seat starting jumping about 3" in the air and the steering wheel shook like mad. I pulled over and with everything so new did not know what to do. I started back on the road and drove slow home. I looked under the truck when I got home and ther was alot of snow packed underneath. The next day it had melted out and truck drove fine. We never had snow again until yesterday, which was almost the very same conditions. I went to work and when I came out EXACTLY the same thing happened. My steering wheel shook so hard I could not hang on to it. I got home and the next day it was fine. I only have to drive 2miles home. I cant imagine going any farther with this event. There is no doubt in my mind we will here more of this from others as soon as the snow starts. I have no idea what to do, I am going to the dealer on dec. 9.
