The only weak link
(πχεγεϊ ϊεψτδ)
I know of are the birfields in the front
they will break if abused, but its not very likely to happen with an open diff and tires smaller then 31 inch,
If the hubs(LOCKERIM)
are kept in the 4x4 position for daily driving the birfs will wear out
they will make the familiar klink klink klink sound when turning, just like a worn out front wheel drive axle shaft......hope that helps!
