my truck has 75 k miles, every u joint on the truck has needed replacement as well as the carrier barring. not to mention ball joints and tie rod ends but that is another story. when most manufacturers are offering longer warranties, dodge drops the 70k powertrain warranty they had been offering on all our trucks. mine is an '06 so I had no 70k warranty. I am wondering if the deplorable u joints made dodge drop this warranty. as the front u joints in particular are much more involved to change.
