The Witch started intermittently making a deep tire skip noise like when an airplane lands, upon inspection I found my rear guibo was shot and since it was only 18 months old I was pissed.
Found that the transfer case oring #27107537631 would leak through #27107539265 and caused oil to come out the output flange and it degraded the guibo. All three changed and so far she's dry.
If you have a strange degradation of your guibo check for slow leaks and just to note there wasn't any noticeable oil wetness due to road dust and it only leaked occasionally when the seal, o-ring lined-up.
See damaged guibo...
