Some crossing of thoughts here, I think. Grease nipples on track rod ends are a new one on me, and the gungey one in the photo needs a good wipe, but Cain doesn't supply covers for track rod ends as far as I know.
I would imagine that if you put grease in, it's got to come out somewhere & the rubber boot cover must eventually give, surely..? Or is it me..?
I'm almost certain my 105e had nipples on the four track rod ends. Grease sparingly or you pop the covers, just like UJs.
