"Fairly tight," and "self locking." So am I hearing right that I should go back tight and not worry about the thread count or marks? Right now it's just snugged up to the thread count prior to removal. It's loose enough that I could take it back off with a 3/8 drive ratchet if I had to.

The thought that the bearing could be worn or maybe just loose crossed my mind when I removed the nut because it didn't fight the impact much at all. I have heard a slight whine at highway speed that goes away when I let off the throttle. Not sure how long it's been there because I have to listen hard to hear it.

I'm not driving the truck until I get it figured out so at least I won't be making it worse.

Thanks for the info!
