Since it will go into HL and Low it sounds like your linkage is correct.
Sounds like it will only drive with front wheels.
Put it on jack stands(all wheels off ground). When in High the back wheels should be the only thing turning with force. Usually most turn but you can stop all except at least one tire on the back. Have some Marines hold the tires and see if one will continue to spin(you might need to give a little throttle). Also note the rear drive shaft as well. When in HL one front and one back should turn. Low the same thing. Check to see if the rear drive shaft is turning or can be stopped. If it can it is probably the transfer. If it is turning and can't be stopped rear diff really bad. Diffs usually cease but it may be so bad that power is going in but not coming out to wheels.
What repairs were done to the trucks?
