Don't wanna start another oil mess but remember SAE 140 was the replacement for the SAE 160 stuff like SAE 90 was the replacement for the SAE 110 stuff . Multi weight is NOT THE SAME as straight weight gear oil . I just use straight SAE 140 in the rear,tranny,u-joint & steering all the time . Some have different ideas on this but I prefer what Henry said to use . The rear & tranny I fill to the bottom of the fill plugs . The u-joint only calls for 4 oz & if overfilled it WILL LEAK .
