Hmmmm...I find this odd. Being everything Xray is based on the highest quality, why would they release a prebuilt ball diff that wasn't built right? Little or no grease in this case.
And why did they prebuild it in the first place? Anyone buying an XB2 kit (myself included) would surely want to build arguably one of the most important components of the car.
So was it straight from Xray or did RC America do this on their own? I don't want to look a gift horse in the mouth 'cause I would rather have a free ball diff with no grease than no ball diff at all.
