That was definitly caused by lubricant breakdown & reusltant metal
contamination. My hunch is it the vehicle was overloaded or got overstressed
towing something beyong its capacity. The giveaway is the scoring on the
outer axle bearings & the axle shafts.

FWIW, the Grand Cherokee factory maintenance schedule calls for 12k mile
differential fluid changes if it's used for towing & heavy loads (i.e.,
severe duty). It also calls for an 80w-140 lubricant in the rear axle in
those cases.

That thing had to be growlng like a pack of mad dogs for a long time, too.
Would have paid to look into it earlier.
