Thanks for all of the replies, I will show them this thread before they attempt the repair in Boston. I have ordered 2 STEMCO seals (just in case) to be overnighted to the repair place we will use in Boston. Quick question: do the seals come with a wear ring, or is it a separate part? I am not sure, if this point, if the wear ring was ever removed even though I told them to look for it. If it was removed, then I am not sure I can get my hands on a new one if it doesn't come with the STEMCO seal. I am hoping the problem is the wear ring, because the NAPA seal and the National seal both failed within a few hundred miles of installation.
