Arriving early to Diff Works in Riverside, California, the shop owner and gearhead Steve Post began by placing the F-150 on a lift, removing the wheels and tires, removing the 10 diff cover bolts, and then draining the old fluid. Then, he removed the U-joint cap bolts so he could swing the driveshaft to the side. This allowed him access to the front pinion nut that he busted loose with an impact wrench.
