I am pulling prop shaft to run mondo and I pulled the four bolts connecting rear prop flange to input flange of rear diff, and now I have gear oil dripping from union of flanges. What? How could there be gear oil there??
its more than likely run up pinion thread ,pinion has a collapsible spacer so dont undo bolt/nut unless you know what your doing,undo ird end before unbolting carrier bearings front cv gaiter is easily damaged
