Outer Limits 4x4 Board

I need a diff fluid replacement on my fourby, my inner axle seal is busted and im pouring out diff fluid, what's a good trusted fluid?

Dot 3 or dot 4

What sort of diff is it?

Normal/locker/LSD

Any reputable diff oil will do. Lsd will need special oil or friction modifier added.

repair the seal first, I have found redline oil to be very good, bit exy on price thru, other wise penrite oil is good . oil recomendations here http://www.datateck.com.au/Lube/PenriteAus/default.asp" onclick="window.open(this.href);return false;
