RE: Leaking axle
I just changed my diff fluid yesterday (Royal Purple 75-90) and was amazed at how loose the drain and fill plugs are. I took absolutely no effort at all to break loose the drain plug. Mine showed a "stain" on the bottom of the diff where it was apparently seeping out. I had water in my front diff from my flooding incident from a few weeks back. Some metal shavings on the plug, but not enough to worry about. Truck drives ALOT smoother with the new diff fluid.
