I came across an AWD Caravan in the junkyard that had the trans removed but the PTU was still there so I got a good look at it. It has a rather weak looking hollow splined shaft, similar to the stator shaft on an auto trans, to drive the rear wheels. This shaft is directly driven by the diff housing, while the right side front axle goes through the shaft and into the diff side gear. The PTU doesn't have the same bolt pattern as the output housing we're using but it could be made to fit. I don't think I would trust that shaft, though, unless it could be beefed up.Ondonti said:Im also guessing there are no actual facts to support strength comments about the 3.8 awd setup. Just hearsay.
