Axle and Gears and mud O My

Ok this is more of a question of personal opionion.. My Dana 30 front axle had nothing but mud and water in it... This is a new purchase so I really dont know the history and I made the mistake to just run it on the trails with out looking at it. Well the Pinion gear is now shot... the ring looks ok? but you can tell it has had water in it for awhile and no gear lube... Should I just put new lub in and replace the ring and pinion gear.. Or should I just replace the spider gears also.... they look ok but it has been running on mud instead of lube... What are your thoughts??? I was thinking of bitting the bullet and put an ARB in... Or I was looking at eaton electric locker but I dont know much about them...

Once you pull the parts you'll be able to do a better job of inspecting the hard facing on the gears. If there is any pitting at all, replace them.

Better yet, as you mentioned, now would be a good time it upgrade if the old budget can handle the expense. Having something more than just an open diff really comes in handy on the trail.

Good thing you discovered the problem before everything totally grenaded.

I guess I need to clean the mud out real good and see what I am up against... So what do you think is better? an ARB or eaton?

ARB would be better than Eaton I think... Also dont rule out the new Yukon Zip air locker. they are newer on the market but have been getting really good reviews from people running them. Also about $200 or so cheaper is nice also

Don't forget to take care of your axle vent, sounds like a problem there.
