Thanks for all the replys, I think I got my question answered, I found a transmission and differential shop that will do the work, My insurance company told me when they tear it down they will send out an inspector and if the parts are damaged in some way and noticible they will pay for the tear down and whatever parts need to be replaced, So by your responses there should be something noticible that is causing the really bad howling noise either the bearings, gears, etc. Thanks for the help once again from the Crossfire Community
