Tighten the nut until you can feel resistance when turning the yoke back and forth, check torque load. Pinion deeper is less BL without changing carrier shims, pinion shallower is more BL without changing carrier shims. Because aftermarket gears can require different spacing than the OEM set, you cant use the old shim spacing. So, What Happens When a Pinion Bearing Goes Bad? Also have the preload on the carrier bearings nice and tight so it can't move around. In a nutshell, when gears are misplaced or set up inappropriately, driveshafts appear to be bending, or one unit of the differential comes into contact with the pinion gear, which will put pressure on gears, causing a pinion bearing noise. Seems I will not be able to achieve both spec backlash and gear pattern. Predatory and parasitic wasps keep populations low. Much more of the gear tooth surface has burned off than in the example above. My objective was not to reset the Pinion pre-load, but to increase the Pinion pre-load incrementally until Pinion movement was eliminated.
