That's the one. If you loosen that one all the preload goes away. My question was how the dealer re preloads those bearings.
Behind the nut is the flange, behind the flange is the tail bearing, then the slinger (washer like), then the crush washer (a hollow cylinder shape with a bludge in the middle to help hold preload) then the head bearing, then the pinion head. As you tighten the nut, it tightens the nut against the flange and puts preload on the opposed bearings. That force is in the 1000 lb to 1500 lb range for max bearing life. This value is determined by the bearing manufacture like Timken. How does the dealer get it there. It's not a torque value.
