It has shuddered day one for me. No odd noises running on flat ground except a clunk/ metallic one over rough patches. I think that one is the rear prop shaft and it's sloppy u joints and spline. I might see if the dealer has a new one and see how bad they are. If its nice and tight, I'll pick it up. I have the spring part number from the pic, so I'm going to try that. I will also check the diff oil for metal just in case. If there is, there is a new outlander calling my name.
