I have a Warn on my rear Dana 44 cover and just received a Rugged Ridge version of it for my front Dana 44, I don't see any differences other than the RR doesn't have the W cut out of it. I got it from eBay at

I'm replacing my front Barnett diff cover (yes, the horror of that thought) with the stock cover and the RR guard because I've had a very irritating front diff leak since installing it. After multiple, multiple attempts to get the Barnett to stop leaking, I gave up. It even leaked after Blaine sealed at after replacing the front inner seals when I was up there for some other issue. Nope, the leak is not the Rubi Dana 44's drain plug on the bottom, and the housing is not cracked.
In regards to giving up trying to get the leak stopped, I first used a Lubelocker gasket and it leaked. Then Permatex Gear Lube RTV, finally multiple times with Mopar RTV. I've cleaned my driveway one too many times to let it continue leaking... 1-2 drops a day builds up both on the driveway and, ultimately in my brain. My TJ doesn't leak from anywhere else so it doubly bothered me.
My previous Barnett (actually its predecessor from T&J) cover on my previous TJ's rear Dana 44 didn't leak.
