Depends on the 6.5
No, I replaced mine as PM due to forum paranoia and to get a rough feel of what the rubber on my HB looks like...
I ended up doing a Power steering pump R&R chasing that noise thinking it was that, as it was whining a little anyhow. It was when I had my shroud off and fan out that I saw it hitting the bolts. I put my OEM back on as I never through it away (for this reason)...
Saving junk paid off. FWIW the NAPA part said CHINA right on it... go figure.
Went to NAPA the other day and they pulled my receipt from computer (cash pay) on the pulley as I didn't have my receipt.
They found it, and I found out it comes with a LIFETIME warranty. They printed my receipt out, so at least I can get a replacement. Gonna be a long lifetime if they only last a month.... Hopefully the next one I get will be better. But now I have oil pan to deal with.
