Maybe they switched to the cast iron version for the V8 models. The
4.0L equipped JGCs sure have aluminum D44 housings. :)

It was the ZJs that Chrysler assembled Dana's 44 ring and pinion in

be tied in the computers that monitor the Anti-lock Brake System. I
don't think it's possible, like you could buy the whole car complete for
