Doesn't grumble when you rotate the wheels, no slop top to bottom or left to right.
Sound starts building around 50+ freedom units.
Not the tires, just dumped my RFT and put on snows, no difference.
No tears in CV.
Does not increase frequency with speed, only volume.
Any thoughts?
Had a bearing fail with no signs?
I'll probably replace it anyhow since it's only starting to bug me, maybe hasn't failed enough?
Still sounds like a bearing. Slop comes later, as does enough grit to hear/feel turning with your hand.
