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

On my F150, the transfer case was super simple. Pull the drain plug, let it drain, and refill. The rear differential requires removing the rear half to drain, reinstall and refill. For the front differential, I used a pump and removed as much of the fluid as possible and refilled it. Total job took me about 2 hours.
