Dick, look on Craigslist before you start paying for shipping one to you. I have seen quite a number of Dmax trucks being parted out in my area (Phoenix). If possible post a picture of the crack after you pull the rear end. I have never heard of someone cracking the housing on a Dmax differential without being in a bad wreck. I guess this something else I need to watch for on my dually.
Take care of your self and get the respiratory infection fixed before trying to fix the truck. I know several people with a similar infection. Many people here in Az. think it is being carried into the US by the illegal invaders at the southern border. Thanks Obama.
Good luck
John
