331 rear differential

I have a 2015 XLT FX4 heavy half. It is the super 8.8 with the 31 spline and 12 bolt cover. I cannot find a rear differential bearing kit for this truck. I have had it down for two weeks and have been on line to many parts centers as well as all the local parts dealers, can someone tell me what bearings or bearing kit to get for this truck.......tired of sending the wrong ones back😡

The super 8.8 is relatively new, so parts are going to be harder to find. Have you tried a dealer, either local or online?

That's for the front axle, the 8.8 in 2015 went to a HD not a "super" there is also no such thing as a "heavy half" F150. The trucks with HDPP are equipped with the larger 9.75 differential. The parts are easy to get and any dealer can look them up by vin number. You can also order them online from Tasca or Ford Parts Giant. The same carrier and bearings fit the 2015+ mustang.
