grease fittings

[Richard Stamile]

Has any one tried the kingpin bolt center drilled with a very small hole either from the top or bottom of the bolt at the beginning
of the hole opened wider and threaded for a grease fitting then a hole drill across to feed the kingpin and collar, if grease holds grit from sand and causes wear
it would not be as bad if you pushed the dirty grease out and feeding with fresh clean grease , of course there if the issue of will your kingpin bolt being
not as strong not saying i am going to try this just thoughts of others or maybe some have tried this already
