Nevermind! What thought it was turned out to just be the clutch on its way out.
I called around and luckily found a Severe Duty Hayden Fan Clutch.
Two hits with a hammer and chisel knocked the old one loose, old one out new Hayden installed in less than ten minutes. LOL I was secretly expecting agony getting the old one off, but she popped off like I knew what I was doin.:woohoo:
but how much is that hub bearing from cummins these days anyhow?
