BRO has diffrential armor for sale now. I have never seen it before. I assumed our diffs are tough enough but maybe I need to get some of this armor being they are only $26. Check it out! Diff Armor

 

What happens to the drain plug??

 

Looks like nothing happens to it, its still exposed on the bottom of the axle. That plate only covers the front of the diff. I run armor that removes the drain plug altogether and replaces the round axle bottom witha flat piece:

And in answer to how you drain the gear oil? Simple, pull the two bottom studs around the 3rd member to drain it.
