I was at the Off Road Expo in Pomona this past Sunday and got to talking to a rep from a drive line company. I was asking about the shudder that our trucks are famous for. He said that something that his company has done in the past is to squirt silicone the "open" areas of the rubber surrounding the center support bearing carrier. By "open areas" I mean those "cut outs" (I don't know how else to describe them) between the bearing and the metal bracket. Apparently it keeps the rubber from flexing so much which in turn reduces the shudder. It makes sense. Anyone ever heard of this before? Or tried it?
