Gearbox, Trasnfer BOx & Rear LSD Oil For LJ70 2.4 1992

Hi there. Can anyone reccomend a decent oil to use in the transfer box, manual gear box, front axle & a suitable oil for the LSD.

Can you use a fully synthetic in the gear box, does it make a difference from a cold start?

Would would your choice be for the manual gear box oil & transfer box & fornt diff for a LJ70. I planned to use semi synthetic Miller TRX 75w90 semi synthetic basically for everything except the LSD & Engine.
