You have been on here for many years, not much more can be written on the subject.
Yes I have been on for some time, but have NEVER have worried too much about them cuz we hardly went long distance w/ old coach and it was inspected every year in NY and just like PA, 1 wheel has to pulled off and dealer never found anything wrong and that coach too had zerks on end of axles. Perhaps in the 12 years of ownership of the old 1, they may have been changed 1x don't recall exactly. So I was just simply asking if there was a right/wrong way on this. I know everyone has their own take on things, but from all those takes, one can come to some kind of conclusion wether or nor not others agree. Just like changing oil and brand of oil. Some say dump every 5k miles, others every7500 miles. Some say Rotella,others say Delo. We all learn from others despite how long we've been around.
