It is not "technically" a Dana as a Jag rearend might be. It is more appropriately an Australian Dana which, those down under can correct me, is a BTR Hydratrac(k?). I haven't seen much info on how they are, or aren't, different than say a Dana 44. Or even if any parts or interchangeable between the 2. I yould be pressing for a warranty resolution as well. This may be voided if rear lubes were changed and not using the correct lube or additive. That wouldn't seem like something needing done so early.
