Chaning Differental oil ???
Have an 03 F350, 90K miles, how often should the diff. oil be changed ? Ford lists the oil that came with is as synthetic. We do about 1/3 towing and the rest around town. Thanks

As a person who just dropped $2,440 on a rear end rebuild I'd do it now. My oil was last changed by myself around 5 years ago and now wish I'd done it more regularly. Oil is cheap comparably.
While that's true, it's also no guarantee that your rear end wouldn't have failed even with fresher oil.
Can't see the differential, so can't say for sure. But what I can say is that in my trucks, changing the diff oil at recommended time made temps run lower. (Transmission made more change).
