I would plan to change the gear oil and clean the magnet on the fill pug. If the plug is absolutely covered full I would clean it, put it back, fill the diff and run it more to clean out any additional filings. Here is a drain plug covered with filings and a shot of the cleaned up drain plug and fill plug from a 2008 3/4 ton Chev.
How many miles?
