OK! It's not as bad as it sounds but I just rebuilt the center diff on my EB48.4 and after tightening the screws the diff is pretty stiff and I can literally feel ever tooth as you spin it. I loosened up the screws to relieve the tension and barely tightened them again. It's a lot easier to spin the outdrives but you can still feel the gears meshing. Is this normal? My rebuilt rear does this ever so slightly and my front diff not at all. And those screws are tight, I know it. Should I try two gaskets or would that create too much space inside the diff case and invite the gears to eat themselves. Whose got the knowledge on this one??? Thanks again!
