Dana 60

[guh2stroke]

I have a 93 W250 4WD with dana 60 axles, shoul I overfill them at all, in the service manaul it says not to because it will cause the oil to foam, thanks to all who respond, Alex

I would use a quality gear oil at the recommended level. If you are towing, then I would consider a aftermarket cover with additional capacity and/or cooling.
