Went on a journey in the 715 today to pick up a power steering gearbox. It was free from a 70 something waggy-yay! On the way there I start hearing a little grinding on occasion. On the way back it starts again and finally I get the severe binds somewhere in the drivetrain. Had to call the wife to pick me up, only to drive back with the trailer and get the barely movable 715 onto the trailer. The rear seems okay based on jacking up each side and feeling how it moves so I think maybe transfercase. Anyone experience the jerk-jerk-jerk from a T-case before? It feels like ring and pinion broken but I haven't torn into it yet. Nothing felt hot, I guess I'll just start opening things up till I find it.
