I was informed that I needed a new drive shaft, because there is no repair for this drive shaft because its only one piece and the carrier bearing is out as well. there is a clunking noise in the drive shaft. I have had it checked out by 2 different mechanic and both of them say the same thing, I was also told this should be covered under the life of the vehicle because its a part of the drive train is this true? My transmission mounts are loose it gyrates. This is all I see at this point.

The truck shifts into 4X4 high with a loud bang and makes a whistling sound that will drive you nuts. The dealer says this is common with all new F150s and there is no problem. BULLSHIT!!
