Greg, I agree with your mechanic. If you have IRS then the differential lube is contained in the "pumpkin" and never gets to the bearings. You probably cannot even pack those wheel bearings, only pull and replace with aid of special tools.
Either a fluke, tons of miles wearing it out, or you were really high on tongue weight. You say 5000# boat. Was that with or plus trailer? Rigs are usually over the weight we think they are. Now say you hitched with a jack of some sort and really have no idea what percent the tongue was. Could easily have exceeded the axle rating. The max tow rating of the Explorer is probably with a weight-distributing hitch [like travel trailers use] that spreads the load among front and rear axles. Boat traler hitch not only doesn't distribute, it gives the tongue weight leverage against the rear axle because the distance it's behind the axle.
