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.
