What is your question?
I have never heard of this before in 52 years of owning automobiles including Cadillacs, etc? The car has 48,000 miles.

According to the Alldata information there is not a manufacture recommended interval for the rear differential. Most likely the vehicle came factory filled with synthetic gear lube and is considered lifetime. we recommend gear lube drain/replenish on time and mileage 60k would be a interval that I would be thinking about changing gear lubes.
