Behaving badly

[EJ-Fresno]

I just replaced my AOS as preventive maintenance as well...
Will be following up on this one too.
Thanks.

I just don't get that. We hear so many stories about people getting bad AOS's right out of the box, or new ones that fail after a month or so. Why on earth would anyone replace one that is functioning perfectly and has done for many miles? I wish I had money to waste like that.

That's the purpose of preventive maintenance, trying to anticipate issues.
If I do apply your theory, I'd have to wait for something to break, cause damage and then fix it, for a higher cost and more trouble.
There are risks both ways... Choose your side.
