Greg, I just put in that missing zerk as Jim pointed out in my pictures on page one of this subject. I was able to pump the gun about three times and that was it. From there on it was solid. No amount of reasonable force would get any grease to leak out of the joint. Is there something wrong with them?

I just checked my records and they were put on in 7/70 and have about 135,000 miles on them. I don't notice any problems.
