I've just been replacing a lot of parts on the latest buggy, the new front driveshaft U-joints have flush-type grease fittings on the bearing cups. I've never encountered these before, they're small countersunk cups with a check ball, nothing like a regular zerk. Not flat like an Alemite fitting, either. Nobody seems to have the mating nozzle for a grease gun, counter monkey at the parts place just gave a shrug. Anybody know what's supposed to be used with these things and where to get it? I can always use them like grease plugs, just unscrew them and put in a regular zerk come time to regrease, but if I could get the proper nozzle at a reasonable price, I'd go for it. Google didn't turn up much besides the fittings and the data pages on them just said to get a flush nozzle for the grease gun. Big help.
