does anyone know the size of the rear diff drain and fill plug? i was fighting with it last night and lost.
finally this morning i gotta 15/16" on it and got it off but its all rounded and messed up so im thinking about replacing it. im thinkin maybe my diff breather is plugged up cuz it was so ridiculously tight maybe there was a bit of a vacuum? does that make sense?
Yeah, the vacuum idea makes sense but I dont think it would be strong enough to make a noticable difference when trying to loosen the plug because it's such a small area. Have you tried ttwisting the breather to make sure it's loose? If you can twist it around with your fingers, than it shouldn't be clogged.
