Remove the pinion yoke with a 1 1/16-inch socket. Save the shims on the pinion. These help set the preload rating. When installing the locker we used the OE bearings. If you use the same gears, make sure the height where the new ring gears sit matches the old carrier height. Since we were unable to pull the pinion race (a sleeve that fits between the pinion and the housing), the guys at Tri-County used a bearing spreader.
