Yeah, A couple of years ago, my ZJ did the same thing [94 Limted, 5.2L, Fulltime 4WD w/249 T-Case]. It would only do it after I drove for a while. Turned out to be the Viscous Coupling. A very expensive part [seen 'em on e-bay for $450]. Mine was under warrantee at the time so it cost me $100 in deductables.

The usual check for a VC failure is to drive tight figure 8's and listen or feel the wheels hop.

	Viscous Coupling A speed-sensitive device located in the transfer case that transmits drive torque between the front and rear driveshafts when wheel-slip occurs. Viscous couplings are typically used on all-wheel-drive vehicles and vehicles with automatic and on-demand four-wheel-drive systems.
