For this one nlgi0 or 1, lithium ep moly grease (cv axle wali kaali grease), nlg12 also can work but it gets flung out to ball.
Nlgi3 is garbage, might as well put a bar of soap inside.
Toyota originally filled it with nlgi0 stuff (same as land rover oneshot grease). Its a semi fluid slumping grease.
But in service manual specify lithium with moly nlgi2, I have found that it can work as long as the 4wd is used often and the right quantity is used. I still prefer the semi fluid type or atleast cv joint one.
