Since we don't often do this, and we didn't have a pinion depth gauge,we'll show you how to set up the gears without one. Put the pinion gearin the housing, then install the front (small) bearing (be sure to oilthe bearings before you install them). When the bearing is far enough onthe pinion shaft to start the yoke nut, tighten the nut to 240 lb-ft. Ifyou have the proper bearing preload, you should have some resistancewhile turning the yoke with a torque wrench. A new bearing should be setat 20-30 lb-in, while reused bearings are set to 0-15 lb-in. If it istoo tight, add shims. If too loose, remove some.
