How easy to pull furnace fan out?

If you haven't done so already, try some creative ways to get some lube in there before you pull it out. I've used long tubes of the diameter of those on sewing machine oil (which works like a dream, BTW), specially bent lengths of coat hanger with q-tips taped to the ends and even a length of broom straw dipped in oil. This has given me years of extra service on fans from those that are seldom used to ones that work for hours a day.

Hey, just did it again today. The fart fan in my most used bathroom started squealing and growling again. A little sewing machine oil quieted it up again. Last time was about three years ago and it runs at least 2 hours a day. Installed in 1992. Now it's kinda becoming sport for me.
