A cheap alternative figured out at Moab last time...to get me home!!
Disconnect the TOD computer under passenger seat,
and remove the spline locking discs from the end of the hubs.
Source two cheap sponges to use as gasket material to replace disc thickness...tighten down with the dust caps.
Sponges can be trimmed for 'looks'!

This stops all drive to front shaft/axle etc.
I've been running like that since May..no issues.
