Based on the dealer records / receipts from the previous owner, it doesn't appear the diff fluid was ever replaced so I decided to do it today.
Removed the full plug first
Removed the drain plug, oil didn't look bad but there was stuff on the magnet
I filled w supertech 80w90, will run for about 3k miles as a rinse then go with a full syn 75w90.
Took it for a drive and it runs normal and no whining.
