That is rather large, did you report it to the dealer or Ford for quality control by Ford. They have to have a chance to inspect the axle for damage, it may need replacement of the axle, these things have a 60000 mile warranty repair for 5 yearsAdd me to the list of people who changed their rear differential fluid and found nasties. 6200 miles and should have done it sooner. Dark and found a 5/8" long machining chip stuck to the magnet, some other fines in drained oil. I worked in a machine show while going to school, so I know what a machining chip looks like.
At least it was on the magnet.
This is what I did also. Used some sealant for use with synthetic oil. Was going to do both but realized before I drained the front front (luckly) I needed another quart of fluid. (bad math) Used Valvoline full synthetic 75-90. Always tomorrow when your retired.
