Hi Jim,

The GL rating of a gear lube can be a good debate(usually with a good
"refreshment" supply). However for the Hypoid final drive gears in our
Vanagons & all type IIs, the most important consideration is that any
transmission gear lube be equipped with the Hypoid additives approved
for Hypoid gear lubrication. GL 4 or GL 5 ratings may not count as long
as the oil is API approved gear oil for Hypoid gear use.
