Any cautions if converting Final Drive to Synthetic?
« on: August 03, 2022, 04:21:50 PM »
From the smell test, I still have the old spec 90wt Hypoid in the final drive.
I assume the consensus is Synthetic is better. Is there anything to be concerned about simply draining and filling?
Also, is there a direct replacement spec for 90wt?

No good turn goes unpunished, but it's fun to keep trying.........
