I bought this truck used and it had a roar in the rear differential. It turned out to be a pinion bearing and race was bad. I bought all new components for the rear differential. New bearings, new carrier, new spider gears, new axle gears, new ring gear and pinion. My problem is with all the new stuff I have a whine around 43-50mph and is loudest at 46mph. The whine is there when accelerating and deceleration. I have the backlash set at .007 and have attached 2 pictures off the drive and coast pattern. I can say going to a thicker oil did quieten it down some. Anyone have any suggestions?
