Tie Rod End Grease Seal

[DrG]

After changing my oil, I shot a little grease into the zerts and noticed that I was have a small stream of grease coming out right in the middle of the rubber seal on the passenger side tie rod end. I am not saying it was losing grease at the upper or lower edge as when you overfill it, but this is a tiny hole in the center of the seal. I could reach up there and push on the rubber and more would come out. Is this a leak or is there an overflow valve in these? I didn't see this on the other side and of course, I turned 36000 miles last month too.
