Sent some pictures by e-mail, which pretty much show as similar to the axle/diff from e-bay I posted above.
The noise is a loud drone. Its certainly not a whine or graunch. It is certainly coming from the diff.
What's the recommended path from here? I will be in charge, but mechanic will do the work if I am there and at least pretending to participate.
Is there anything more complex here than unbolting and dropping the prop shaft, unbolting the housing from the front and then withdrawing it? Do I need to remove hubs and therefore withdraw halfshafts?
Should I then look to replace bearings or cogs, or simply replace the entire thing?
Clearly if the diff can be repaired without moving the diff housing, its actually not that big a job. Aailability of diffs & bits is good, provided one does not require an import receipt, a warranty, or pretty much anything else, actually.
