Jeep dealers used to, and probably still do, sell a friction modifier additive for the differential.
It was a long time ago so my memory is hazy, but a Jeep dealer told me to operate the differential a few times by driving with one wheel on a less grippy surface than the other. I think that the differential sticks, so that in effect you don't have differential operation, and the half-shafts wind-up.
