Man you must of come down on that thing pretty hard to cause a leak. I landed on mine and dragged it down a rock and had no issues. I'm not sure but by looking at the pictures from 4xguard it just looks like the guard only protects the cover from being smashed into the gears not from peeling it back we might need to get some feed back on this from them. I would think you could just weld a piece of steel to the bottom of the diff that over hung past the cover a little bit so you could just slide right off. I'm just brain storming I guess.
