rear diff oil change question
I changed the rear diff oil on my 05 f150 last year with 60,000 miles on it, only put about 2000 miles on it since then, I went to check it yesterday just for fun and the new oil already has some metal filings in it and some on the plug, is this normal? I don't have a lot of experience with rear diffs. my boss tells me not to worry about it if its not making any noise, which it isn't, but I have a long haul coming up here in the next year 3000 miles and don't wanna have any problems on the road. no large chunks just can see some shimmer in the oil when in the light other than that the oil still looks very clean

since its not limited slip then you dont have to worry about the clutches getting destroyed and it doesnt sound like there is a lot of metal in the fluid, you should be more than ok to take it on your trip. i would definitely want to get a more thorough inspection done before your 3000 mile trip though.

Not the best replies in this thread.
You are fine.
Typically if the oil hasn't been changed before, there will be more metal shavings than the stock magnet can hold onto.
Therefore when you change the oil and clean the magnet, you are going to collect some of those shavings that were left behind from before. They won't be entirely new.
Unless you did a complete flush, and wiped everything spotless, I'm betting a lot is left over shavings. If you had swapped gears, or made any changes, 2,000 miles is plenty of time to accumulate new metal shavings.
